Little Champions – Special Exhibit at the Pacific Bonsai Museum

A “Champion Tree” is a specimen that has been measured to be the largest of its species (see “Champion Tree Registry“). The findings are based on a points system that considers tree height, trunk circumference, and average crown circumference (there’s a manual that spells out the details).

Playing on this idea, the Pacific Bonsai Museum is currently featuring an exhibit called “Little Champions” that looks at eight specimens that are native to the West Coast. It’s a great example of the bonsai work that can be done with native material.

First up is an Engelmann spruce that’s been in training since 1978. Harvested from about 4600′ on the slopes of Mt. Hood, this specimen suggests the rugged terrain in which the species thrives at a much smaller scale than the tallest of the species (179′).

Next up is a vine maple on loan to the garden from Michael Hagedorn. It was collected at about 4000′ from a lava flow in the Cascades. (Forgive the netting around the pot – it’s job is to deter critters from digging up the moss.)

The coast redwood below was donated to the garden by Toichi Domoto, a well-known California nurseryman and bonsai grower. Domoto started this bonsai from a three-year old seedling in 1957 and trained it for thirty years before donating it to the Museum (learn more about Toichi Domoto).

In 2018, the museum presented the LAB (Living Art of Bonsai) Project which featured work from bonsai professional Ryan Neil, ceramicist Ron Lang, and furniture designer and craftsman Austin Heitzman (learn more about the LAB). The basic idea was to mix up the order in which tree, container, and stand are created to see what happens.

The composition below started with Lang’s container. Heitzman then created the stand to complement the container. Finally, in 2020, Neil planted the root over rock Douglas fir and this composition came to its initial completion.

Sitka spruce can grow to massive sizes and live to be over one thousand years old. This specimen was collected in a parking lot on the Olympic Peninsula in Forks, Washington. The pot was from the museum’s Decked Out exhibit in 2016.

The subalpine fir is one of a number of coniferous species that takes on a standard forest tree shape at lower elevations but can become contorted and character-filled in more extreme environments. The specimen below, created by David De Groot, is no exception. The container is by Jan Rentenaar.

Balancing summer growth on black pine

Black pines are one of a number of species that don’t naturally produce balanced growth. These pines are likely to produce strong shoots near the apex or at the ends of lower branches and weaker shoots everywhere else.

Of the many ways to balance this growth, the most effective I know of is to decandle the spring growth at different times. I start by decandling the weakest shoots, wait one or more weeks, and then decandle the strongest shoots.

If the tree has small, medium, and strong shoots, I might decandle on three different days ten days apart. If the tree has small and strong (but no medium) shoots, I might decandle on two different days two or three weeks apart.

The basic idea is that you give the weak shoots more time to produce summer growth and you give the strong shoots less time to produce summer growth (see “Decandling, an in-depth guide” for details).

I typically only do this on a handful of trees each year, and some years I don’t do it at all. If, however, I see the need and I have the opportunity, I give it a go. Here’s how this works in practice.

The black pine below has a number of really strong shoots, but the rest of the shoots are relatively weak – a perfect candidate for the multi-day approach.

Black pine with unbalanced growth

I start the decandling process by removing the smallest shoots.

After decandling the small shoots

It’s hard to see the difference between before and after this work as the small shoots in this case were much smaller than the strongest. Here’s a close-up.

Close-up showing decandled shoots

About a week and a half later, I removed the strongest shoots and plucked some needles. I kept three pairs per shoot at the top of the tree, four pairs per shoot in the middle, and five pairs each on the lowest branches.

After decandling

I haven’t shared an update about this tree in a while as I’ve been rebuilding the apex for the last few years (see “Black pine – work in progress“). Now that the new branches have begun to fill in, I plan to wire the tree and refine the silhouette the next time I work on it.

A visit to Peter Macasieb’s shohin garden

Seeing photos ahead of time didn’t adequately prepare me for the literal wall of bonsai that greets visitors at Peter Macasieb’s garden.

Peter Macasieb's garden

Peter has been a fixture in the Southern California bonsai scene for years. I’ve been wanting to see his collection up close and was excited to learn that I’d have the opportunity to visit on a recent trip to the area.

One thing that makes Peter special is that he creates many of the shohin he works with from scratch. Just across from “the wall” are several benches of young junipers, pines, and zelkova, among other species, that he’s been working on for years.

The sheer size of Peter’s collection makes it easy to miss how many different species he’s growing. It’d be fun to visit in winter to see the deciduous trees without leaves.

Tom Vuong’s Giant Trees

I drew a lot of inspiration from my visit to Tom Vuong’s bonsai garden. It wasn’t just the trees, but the way he handled them.

California juniper

Tom came up with many the techniques he uses on his own. This extends to the way he collects junipers, bends large branches, and works on deadwood. He air layers black pines – even cork barks – regularly, and has perfected a method for grafting pines using candles before they’re fully open. Over time, Tom’s hard work has produced a large number of (large) trees that wouldn’t be bonsai without his vision and novel techniques.

A visit to David Nguy’s garden

Getting to know David Nguy over the years has been a pleasure. The first time we had a chance to talk at length was on a trip to Japan about eight years ago. He invited me to his garden that day, and I’d been looking forward to seeing it ever since.

Earlier this year, I was lucky enough to visit David and June at their home in Southern California. What a treat! Their huge garden is filled with a variety of species at different stages of development. Foremost among these species are one of David’s specialties – California junipers.

Highlights from the 47th Mid-America Bonsai Exhibit

This past weekend I had the pleasure of serving as the featured guest at the 47th Annual Mid-America Bonsai Exhibit hosted by the Midwest Bonsai Society. It was a fantastic weekend thanks to the hard work of the organizers and volunteers that made the event possible.

The show takes place at the Chicago Botanical Gardens, a beautiful setting for a bonsai event, in Glencoe, Illinois. I spent Friday morning judging the exhibit and provided a critique that evening. I’m always looking for a better word than ‘critique’ as it’s more of an opportunity to highlight work that’s done well and to provide suggestions for further improvements. The rest of the weekend featured workshops, a demonstration, and plenty of shopping opportunities with the 36 vendors on site.

Visitors come from all over the Midwest making this a great opportunity to catch up with friends from throughout the region – a rare treat as I haven’t had the chance to visit the area recently.

At the event’s core, however, is the exhibit. Here are some of the highlights.

The bonsai collection at the Chicago Botanic Garden

While I was in town for the recent Mid-America Bonsai Exhibit, I had the opportunity to visit and learn about the bonsai collection at the Chicago Botanic Garden. Curator Chris Baker and Seasonal Bonsai Assistant Angelica Ramirez led me through a tour of the facility that included the work areas, multiple greenhouses for overwintering trees at different temperatures, and the public display courtyards.

Angelica Ramirez and Chris Baker

Angelica Ramirez and Chris Baker

Chris is the garden’s first full-time curator. After volunteering for a few years at the U.S. National Arboretum, he was able to secure a six-month apprenticeship at the Daiju-en garden in Japan with Toru Suzuki. Upon his return to the US, Chris received a “First Curators” Internship at the U.S. National Arboretum. These experiences led him to Chicago where he’s served as curator since 2014.

Angelica has also served at both the US National arboretum (as the National Bonsai Apprentice) and at the Chicago Botanic Garden. In addition to working at the Garden, Angelica maintains a database of active ceramicists making bonsai pots (check out her awesome resource “Discover Potters“). She’s also coordinating the American Bonsai Society’s 2025 Bonsai Pottery competition (you can see the finalists on display at this year’s ABS Learning Seminar in Rochester, NY).

Highlights from the 2025 REBS bonsai show

The Redwood Empire Bonsai Society held their annual exhibit last month at the Rohnert Park Community Center in Rohnert Park, California.

This year’s event featured a demonstration from Mike Pistello, member tree sales, and a good mix of vendors. It also included a trees-in-training display with bonsai presented by members who are relatively new to the hobby. It was a well-executed display with different species at different stages of development. Some trees were in plastic pots and some had yet to be wired, but all were arranged carefully and accompanied by accent plants. I hope to see more displays like this in the future!

As for the main exhibit, some of the first trees to greet visitors were large coast redwoods.

Conifers are a common choice for summer shows, but there were a few deciduous bonsai in the exhibit and a pyracantha loaded with fruit that was just starting to turn color.

It was fun to see two atlas cedars in the exhibit, one green and one blue. Cedars are a good fit for summer shows as most of the spring growth has hardened off and the trees are covered with a fresh flush of foliage.

One of the junipers in the show was a “tanuki,” a bonsai created by training a young tree around a piece of deadwood to make it look like a much older composition. When tanuki are well excecuted, they can be hard to discern from much older trees.

tanuki

Tanuki – a young shimpaku, in this case, trained on a much older piece of deadwood

I’m often asked if it’s OK to show tanuki. In general, I think it’s fine to display tanuki at exhibits, and it’s up to the organizers to determine whether or not to disclose that a given tree is a tanuki. That said, it’s far less common for tanuki to show up in regional exhibits. As more selective events by their nature, regional shows typically focus on bonsai with the most prized characteristics which include the age of the tree.

Is it OK to display tanuki in your club’s show? Let us know in the comments below.

Walter Pall bonsai master class

About a year and a half ago, I mentioned that I’d like to visit Walter Pall’s garden. The message got through to Walter (thanks, Jennifer!), and last week I was able to make the trip a reality.

Each summer Walter conducts a master class for students and friends at the Bonsaigarten Munich, a public bonsai garden and nursery created by Thomas Haering in the small Bavarian town of Zorneding, just outside of Munich.

The group meets a few times a year in different cities around Europe. The most recent session brought together Jennifer Price (USA), Andy Bello (USA), Lukas Sirotny (Czech Republic), Maros Belan (Slovakia), Kestutis Gailius (Lithuania), Andrija Zokic (Croatia), Thomas Haering (Germany), and Walter’s helper Benedikt Schwabl (Germany).

The format of the class is simple – everyone works on one of Walter’s trees and the group discusses the work before and after it is completed. Most of the material is collected European conifers with a handful of imported Japanese conifers. The work ranges from initial stylings to refinement of mature imported specimens.

I arrived on a Friday straight from the airport a few hours after the group got started. Already the trees were taking shape.

Right in the middle of the room was a beautiful Japanese hemlock planted on an artificial stone. Walter had selected the tree so I would have a fun project to work on over the weekend.

At times the workshop got crowded. Visitors to the garden – up to ten at a time – would wander through the space as we worked giving the event a lively feeling. Most of the visitors spoke at least some English and didn’t hesitate to ask participants questions as they worked.

The real highlights of the session, beyond making friends and working on great material, came when we gathered to discuss the work. This typically began with the stylists describing what they did to a given tree and what the plan would be going forward.

Lukas had brought a batch of 8 Euro (about $9.40) field-grown yew that made for interesting studies of how to handle rough material.

Andrija and Benedikt discussing a field-grown yew

Walter followed these presentations with suggestions for further development or stories about the tree’s histories.

Some of the stories were unexpected. The European spruce below was collected by Randy Knight years before and has since been maintained by Walter. The tree was one of several styled by Jennifer Price over the weekend.

Jennifer and a spruce

Initial styling complete

A common refrain that came up during Walter’s critiques was that a lot of the material presented “flaws” that made the trees good candidates for less conventional styles. Many had dead central leaders with one or more side branches which had started to grow upward in its place. The result was often a bonsai with multiple apices.

Spruce

For some participants, the event was an opportunity to refine skills that didn’t come up in their daily bonsai practice. This was definitely the case for Andy Bello. Andy is the Assistant Curator at the US National Bonsai and Penjing Museum where maintenance and refinement tasks are more likely to fill his days than initial stylings.

Andy also had the opportunity to style a fantastic pine.

My work on the hemlock entailed moving the top and back branches to give the tree more depth and then thinning the foliage to ensure the lower branches received adequate light. The tree will be due for more detailed work after it recovers from this year’s work.

It was a treat for me to see so many European natives. European spruce, mugo pine, and Scots pine are more likely to be nursery grown in the US so it was fun to see collected specimens in person.

Although it was sad for me to get to the end of the weekend, most of the other participants were already planning the next master class for a weekend in the Czech Republic at Lukas’ garden. I don’t know when I’ll get the chance to visit the group again, but I’ll be looking forward to it when I do!

Amazing pines at Michael Tran’s garden

One of several side trips on my recent visit to Germany took us to Heidelberg to see Minoru Bonsai, the garden of Michael Tran.

Michael, who studied with Udo Fischer, among others, founded the garden in 2009 and hosted several high-profile events featuring international bonsai professionals known as Generation Bonsai.

Michael’s garden features a fun mix of juniper, larch, and oak, among other species, but is best known for its pines.

Mugo pine

It was really fun to see the mugo and Scots pines as they both have unique characteristics that make them great candidates for training as bonsai. Both have relatively short needles with sturdier, darker needles on the mugo and airier, pale green foliage on the Scots. The natural movement and deadwood on both is fantastic.

A visit to the Bonsai Zentrum Heidelberg

The Bonsai Zentrum Heidelberg is a large bonsai nursery and event center owned and operated by Edis Ziegler. A previous incarnation of the business had closed in 2006 prompting Edis to acquire the property, renovate, and reopen it in 2008. Since then, the operation has grown into a premier destination for bonsai, containers, suiseki, and koi.

Attending regional events like the US National Bonsai Exhibition is a good way to gain an understanding of the work happening within a given community. At the National, the community showing trees represents a big swath of the US. As a result, it features a lot of great trees.

I don’t tire of visiting events like these because there are always opportunities to learn about new trees or see trees in person that I’ve seen in photos for years. The latter is true for the dwarf corkbark elm by Sergio Cuan below.

It’s a big tree, and the craggy bark and fine twigs give it extraordinary character. If you’re curious to learn more about the tree’s history, check out Sergio’s account at Bonsai Nut.

Regional events like the National also tend to feature a mix of exotic species as well as natives. The former are often well-developed specimens that took shape over many years.

The native trees in regional events are often in earlier stages of development but offer huge potential for future development.

When it comes to shohin displays, it’s simply fun to see well-executed displays. It takes a lot of effort to create a six-tree display so it’s great when you can enjoy them in person.

It’s also fun to see different takes on similar material, whether species or size and style. There were a number of white pines, for example, at this year’s event. By comparing the branch work on each we can get ideas for how to style similar trees and refine our sense of which approaches we like best.

  • This Sunday the San Diego Bonsai Club is hosting their second Bonsai Blast – a one-day affair featuring vendors, workshops, and demonstrations. Japanese bonsai professional Hiroyoshi Yamaji and I will be doing demonstrations at 8:30am (me) and 1:30pm (Yamaji).

    I’m really looking forward to the demonstration as it’s a departure from the regular format. Instead of completely styling a single tree, I’ll be working with two trees in earlier stages of development for each of the following species: black pine, cork oak, silverberry, lavender star flower, and Chinese quince.

Highlights from the 2025 North American Bonsai Pottery Competition

After a long hiatus, the US again has a juried bonsai pottery competition. After an initial pair of events in 2001 and 2002 and a follow-up in 2015, we now have an updated competition sponsored by the American Bonsai Society and managed by Angelica Ramirez.

Angelica Ramirez

Angelica’s dedication to promoting bonsai potters is unparalleled. Her online database, Discover Potters, features almost 500 bonsai pot makers working in 50 countries. For this year’s bonsai pottery competition, Angelica coordinated over 100 submissions from around the US and a multiple-round judging process that included a mix of professional ceramicists and bonsai practitioners.

The exhibit

Early rounds were held remotely. Artists submitted photos of their work and a prose description of their process to provide context for the judges. The final round of judging took place in person at the exhibit.

Bonsai potter Roy Minarai and I served as the in-person judges. The process was fantastic and one of the highlights of my trip to the National Bonsai Exhibition this year. Before getting started with the judging, Angelica gave Roy and me an hour-long tour of the exhibit providing information about the process by which the containers were made. (The submissions themselves were anonymous.) Roy and I then spent the next hour casually appreciating and inspecting the containers to get a good sense of build quality, design, and usability.

Handling pots can reveal a lot about the build of a container. When there’s a tree planted in a pot, we tend to focus on the suitability of the design for a given tree. On it’s own, one can consider the container’s weight, balance, and construction.

I can’t convey how fun it was to get to handle such well-made ceramic works. It was like visiting a museum where visitors are encouraged to interact with the collection.

Roy and I spent the next hour in silence independently judging the exhibit using a crafty online interface that involved scanning QR codes and using sliders to indicate our scores relating to build quality and artistic merit.

After enjoying the exhibit room on our own for several hours, the awards were distributed, information cards went out, and visitors entered the space. Here are some of the fantastic containers from the exhibition.

A visit to Walter Pall’s garden

One of this year’s highlights was getting to spend time with Walter Pall in his garden. After joining his master class for a few days in Zorneding, Germany, I headed to Walter’s garden to record him talking about his trees. The result was a series of nine videos in which Walter shares stories of how he acquired his trees, how he approaches styling, and what he gets out of growing bonsai.

Walter Pall

For years I’d been wanting to get a better understanding about the work Walter does. Although seeing photos of bonsai does a good job of expressing the basic idea of one’s work, I’ve found that meeting artists and experiencing their trees in person offers a more complete picture.

Walter's garden

Walter’s garden

This was definitely the case in Walter’s garden. Through his naturalistic approach to styling trees, Walter conveys stories about the hardships trees face in harsh alpine environments. A good example of this his “candelabra” European spruce – a tree that has taken on the candelabra form after losing its central leader.

His work with deciduous bonsai allows viewers to enjoy the trees year round. Were he to create a fuller silhouette, it would be harder to see the trunk and branch structure when the tree is in leaf.

Cutback on field-grown dawn redwood

For the first time in years, I have a dawn redwood in the garden. It was a favorite species of mine growing up but I’ve only worked on them as bonsai here and there over the years. After working on one last week, I’m not sure why I don’t see more of them trained as bonsai.

I picked up the tree from Cedar Rose Nursery in Placerville, California. The tree was still growing in the ground when I stopped by, so we dug it up and cut off most of the roots, the top half of the trunk, and all of the branches. That didn’t seem to slow the tree down as it produced lots of new growth over the course of the growing season.

After one growing season in a pot

After one year in a pot

I started work by removing the old leaves but found that small leaflets kept getting stuck between the branches. A small brush made the clean-up easy.

Removing leaflets between branches

Brushing away old leaves

After removing the leaves it was easy to see some of the flawed branching.

After removing the leaves

Lots of opportunities to prune!

Some of the more unsightly flawed branches were “bar branches,” branches that emerge at the same level on opposite sides of the trunk.

Bar branches

Bar branches

Although there are good reasons to keep bar branches on occasion, there was no great benefit to maintaining them on this tree as there were plenty of nearby branches that I could use to create the primary scaffold branches.

The tree looked different after removing several bar branches and thinning branch clusters where more than two or three shoots emerged from the same spot.

I also selected a single leader at the top of the tree. I don’t yet know what my plan is for developing the apex (a single leader? multiple leaders that branch out?), but I do know that I’d like at least part of the upper trunk to thicken.

From here the work was straightforward. I shortened the upper branches and wired the remaining branches to give them shape (thanks Mark and Nicole!).

I plan to prune the top of the tree several times during the growing season next year to give the lower branches time to get stronger. I’ll revisit the structural decisions when I look at the tree next fall.

    I’m a big fan of the event and of the book so I was thrilled when I found out I could make them available in the US. Learn more or pick up a copy at the Bonsai Tonight Online Store.

Pruning flowering quince

I usually aim to prune flowering quince such as boke, toyonishiki, or chojubai in fall after most of the leaves turn color and begin to fall off. In recent years, however, my garden has lacked the cold required to make this happen.

Flowering quince in early January

When this happens, I defoliate the trees and prune them to give them a short break (they usually start blooming immediately after cutback).

White flowering quince after cutback

White flowering quince after cutback – 12″

My goal for cutback at this time of year is to remove any shoots growing from areas where I don’t need them and to shorten the year’s new growth to reduce the internode length and create an attractive silhouette.

When are new shoots not needed? When they’re growing downwards or towards the center of the composition, when there are two or more branches emerging from the same spot, or when they are growing in crowded areas that are unlikely to receive enough light during the growing season.

White flowering quince before pruning

As always with alternate budding species, the goal is to prune to outwards facing buds to create attractive movement in the branches.

Chojubai before pruning

Although little wiring is needed at this stage, each of these trees can benefit from modest branch arrangement with a few wires or guy wires. I try to avoid over-wiring quince as the wire can cut in quickly during the growing season if it’s not checked regularly.

I appreciated that the show included a good mix of deciduous, broadleaf evergreen, and coniferous bonsai. Trees ranged in size from large down to shohin with plenty of trees somewhere in the middle.

It was also fun to see different approaches to the same species. The two coast redwoods below, for example, feature different branch angles, different branch thickness, and different approaches to foliar development.

Special trees at the 100th Kokufu exhibit

Last month the Japanese Bonsai Association hosted the 100th national exhibit, the Kokufu, at the Tokyo Metropolitan Art Museum in Ueno Park, Tokyo.

The event was busier than it has been in recent years, and a larger percentage of the visitors were foreign. As for the bonsai, there was a good number of special trees that are always a treat to see.

Although in recent years it’s become common to see large junipers with massive trunks, it’s the exceptions that stand out the most to me. The juniper below has fantastic character along the trunk.

[Auction Tips]

In preparation for this weekend’s auction, here are some tips to help you get the most out of the event.

  • If you’re interested in taking home an item but want to feel good about the purchase, set limits ahead of time for how much you’d like to spend (and how much above this limit you’re willing to actually bid).
  • Check the health of the tree before setting your buy price. For deciduous trees, check the health of the buds and look out for dead branches or dead areas along the trunk. For conifers, check the number and size of visible buds as well as the color and character of the foliage.
  • Don’t let inside information influence your bids. A long time ago, I stopped bidding on a tree because I knew how much the owner had originally paid for it. It didn’t feel right to pay twice as much as my friend had paid for the tree. This was foolish as the second the bidding ended I remembered that the tree was worth almost double the amount it went for.
  • Take note of who you’re bidding against, but stick to your plan. Once I stopped bidding on a tree because I didn’t think I could keep up with the other bidder. When the bidding ended, the other bidder ran over with a big smile to let me know how relieved he was I stopped bidding as he’d reached the limit he was willing to pay for the tree. Another lost opportunity!
  • Above all, remember that the event is a fundraiser. Bonsai auctions are typically organized by volunteers who work hard to provide us with the opportunity to build our collections and have fun while doing it. Keeping the spirits (and the bids) high can make the event a pleasant experience for everyone.

Shohin bonsai at the 100th Kokufu exhibit

Each half of the Kokufu exhibit features a small number of shohin displays. The exhibit is set up to present the large trees first, then the medium bonsai, and finally the shohin. They’re the last bonsai you see before leaving the exhibit.

Six-tree shohin display

Like the larger trees in the exhibit, shohin bonsai are eligible to receive the Kokufu prize. However, instead of awarding an individual small tree, the award is presented to the top display.

The display above received the Kokufu prize in the first half of the event. The display below won the award in the second half.

A visit to the Omiya Bonsai Art Museum

The Omiya Bonsai Art Museum is a favorite stop of mine on bonsai tours. It provides visitors with a little history about the Omiya Bonsai Village – a collection of historic gardens, several of which are still operating today – and features a courtyard garden with a rotating selection of bonsai.

Most of these trees have been in training for a long time and show a maturity that’s harder to find outside of Japan.

Ume

One reason I come back to the museum so frequently is that there is ample space around every tree. Getting to see great bonsai from all angles is great for studying the trees’ shape and structure.

Shishigashira

The brown foliage on some of the conifers is a response to cold weather. The trees typically green-up when the weather warms in April.

Cryptomeria
Estimated age: 70 years

Ginkgo

Estimated age: 50 years

Some trees, like the ginkgo above, look much older than their estimated age suggests. Other trees are much older than we might casually guess.

Black pine

Black pine
Estimated age: 250 years

Korean hornbeam

More important than age in some cases is the time in training. Each of these bonsai look like they’ve been cared for as bonsai for a long time. This gives them a unique character that distinguishes bonsai from trees found in the natural landscape.

A snapshot of Shunka-en bonsai garden

One of the most common stops on bonsai tours in Japan is Shunka-en, the garden of Kunio Kobayashi. By car or train it’s about 20 minutes east of Ueno Park, home to the Kokufu exhibit, in Edogawa.

I first visited Shunka-en, or “spring flower garden,” twenty-seven years ago. Since that trip, the garden has changed a lot. There are several new growing areas and more than double the number of trees, including these junipers and pines in the main courtyard.

The garden is jam-packed with trees, mostly conifers, in every direction you look.

Although most of the trees are presented for garden display (the facility is billed as a museum) there are a few prominent trees in development, including the maple grafting project below.

Inside, visitors can enjoy several tokonoma set up with seasonal displays. On the day we visited, the display rooms featured a juniper, a chojubai, and a maple, among other species.

Just outside the display rooms, a large collection of deciduous bonsai sat on the ground under the protection of the main building’s eves.
