On March 7 and 8, 2026, the Bonsai Garden at Lake Merritt (BGLM) will hold its 26th annual Mammoth Auction & Sale 2026. This is the primary fundraising event for the BGLM. The proceeds from the event go towards annual operating expenses.

Originally, the event was called the Mammoth Bazaar, which was conducted on March 29, 1992, at the Lakeside Park Garden Center, Oakland, California, to raise funds for the planned Bonsai Garden. Since then, the two-day event has been held every year with few exceptions like the Covid Pandemic in 2020.

The Mammoth Auction features live bidding on approximately 100 quality bonsai trees, pots, stands, and related bonsai materials on Saturday. On Sunday, the fundraiser opens with a dozen or so bonsai vendors who offer bonsai supplies such as bonsai trees, tools, soil, pots, stands, and the like. Subsequently, a large variety of bonsai trees, pots galore, books, suiseki viewing stones, stands, and art objects, are offered for sale at bargain pricing from either donations or consignments. Crowds of excited shoppers show up hours early, lining the entrance of the garden center in hopes of snagging the best deals.

To have a successful fundraiser, there is the requirement for many volunteers to fill the varied roles in conducting the event. It may take 50 or so volunteers to conduct the auction, whereas a similar number of volunteers participate in the second day of sale activities. About a month and a half prior to the event, volunteers take part in cleaning and prepping the bonsai trees and pots, followed by a morning to photograph the sequential order of auction items. A catalog is published for the bidders because of their efforts.

All proceeds from the fundraiser support our annual operating expenses, including the care, maintenance, and essential supplies needed to ensure the bonsai collection continues to thrive.

In 2026, the two‑day event will feature 110 high‑quality auction items, including exceptional bonsai trees and handcrafted stands. There are 17 notable bonsai vendors participating in the second day. The sale on Sunday promises to be exceptionally good for bargain hungry shoppers.

Wine and Bonsai – Bonsai Garden at Lake Merritt

Wine and Bonsai –
Bonsai Garden at Lake Merritt

By Suzanne Muller and George Haas

On November 23, 2025, at the Bonsai Garden at Lake Merritt (BGLM), a special project was undertaken by Kyle Jeffrey and JJ Ignotz. Kyle Jeffrey works for the Woods Beer and Wine Company, Treasure Island, California, as winemaker. He hired JJ Ignotz, a Professional Photographer, to photograph the bonsai trees.

The company is operated by the following:

Jim Woods, Founder & CEO
Matt Coelho, Founder

The photo shoot was accomplished with the help from BGLM volunteers – Gordon Deeg, Yuri Aono, Michal Tiede, Mike Roberto, Ashley Pouliot, Nicole Yabut, and Suzanne Muller.

This was no ordinary project! A total of 19 bonsai trees were selected from among the 160 bonsai trees that make up the collection at BGLM. Weeks before, BGLM volunteers tended to the bonsai trees in anticipation of them being photographed by JJ Ignotz. In taking on the project, a temporary photo studio was set-up within the BGLM workshop. It took most of the day to completely photograph all 19 bonsai trees.

The bonsai tree photographs will be transformed into artistic wine labels designed by JJ Ignotz for the Woods Beer and Wine Company (Woods Beer and Wine Company). The wine is featured at six local bars, brewpubs and wineries in the San Francisco Bay Area:

  • Woods Cervecería – Mission, San Francisco
  • Woods Outbound – Outer Sunset, San Francisco
  • Woods Polk Station – Russian Hill, San Francisco
  • Woods Lowside – Lower Haight, San Francisco
  • Woods Cole Valley – Cole Valley, San Francisco
  • Woods San Anselmo – Downtown, San Anselmo (Opening Soon)

Woods Beer and Wine Company plan to debut their new line of wine labels featuring BGLM bonsai tree photographs and artistic designs by JJ Ignotz from April 2026 through February 2027.

Their wine is sold by the brand name Woods Beer and Wine Company. The bonsai trees will be on the 2025 vintage of wine. They will have seven varieties of wines each with a bonsai tree for its label. They produce various wine types, some of  which can be found on their website (Previous Community Club Releases). The company is a very atypical winery with a number of options.

The wine can be purchased at any of their six bars or brew pubs in San Francisco and soon in San Anselmo. There is also an option to become part of their Community Club.

Every new vintage label for the wines will have an image from a variety of sources. In 2024, the labels included art from local San Francisco artist. One year the labels included images around Treasure Island, and another year, images from the Hubble space telescope.

In 2019, Kyle Jeffrey’s vision for a wine label was to takeoff from the name “Woods”.  The ideas began to form. What was the best way to incorporate an image of a tree or artist who drew trees or design the image of the texture of trees? All these ideas brought them to start doing research on small trees, and Googling “Museum for Bonsai Trees” only to discover there is a bonsai garden across the Bay! He and JJ Ignotz scheduled a tour of the Bonsai Garden at Lake Merritt and found their next vintage label images.

Their beer wine hybrid “Divine Origin Series” won the World Beer Cup’s Gold Medal in 2025. The prestigious award recognized excellence in craft brewing and cider production, and the series has been celebrated for its quality and innovation. The World Beer Cup is referred to as the “Olympics of Beer,” and the Gold Medal is a symbol of the highest level of achievement in the craft beverage industry.

Category 18: Experimental Beer – 129 Entries

  • Gold: Divine Origins Carignan

Surely, the artistry of wine labels merits its own competition format, honoring them as an art form.

Autunm Lights Festival 2025

Autunm Lights Festival 2025

By George Haas and Randi Keppeler

The Bonsai Garden at Lake Merritt (BGLM) proudly participates each year in Oakland’s Gardens at Lake Merritt Autunm Lights Festival.

The Autumn Lights Festival is the annual fundraiser held each year for the Gardens at Lake Merritt. The Gardens at Lake Merritt were established more than a half century ago. They are a number of themed gardens with varying levels of upkeep. Volunteers provide much needed maintenance assistance to the City of Oakland’s gardening staff. The Gardens at Lake Merritt are a “tranquil oasis in the heart of Oakland and provide enriching public programs.”

Autumn Lights Festival occurred over three magical nights: October 16, 17, and 18, 2025! This year was the 14th year of the annual event.

The Autumn Lights Festival is hosted by the Friends of the Gardens at Lake Merritt. Friends of the Gardens at Lake Merritt organization comprised of all  volunteers, formed in 2004. It serves to partner with the City of Oakland to enhance the seven-acre collection of themed gardens in the very heart of Oakland.

By supporting the diverse plant collection, habitats, demonstration gardens and landscapes of the gardens, Friends of the Gardens at Lake Merritt work as a learning resource and a serene location for the public to connect with and enjoy the beauties of nature.

A lot of credit belongs to BGLM volunteers Randi Keppeler and Rick Medress for planning and creating BGLM’s role in Autunm Lights Festival. Randi is the creator and artist for the yearly event. Rick is in charge of the low voltage lighting. Preparations for the event have increased exponentially over the last 14 years. Randi’s contributions to design and works of art never seems to end, and Rick constantly comes up with ways to place low voltage lighting so that every bonsai and garden feature receives the visitors’ attention.

BGLM closed down six days before the event in order to set-up the garden’s array of art forms and lighting. Volunteers worked during those set-up days in staging the bonsai trees and many garden features. Volunteers are also active as docents for the three nights of Autunm Lights Festival.

Each night of the event, four to six docents provide information about bonsai and suiseki viewing stones and ensure the physical security of the garden. The hours of operation are 6:00 to 11:00 PM. The event goes on rain or shine. Luckily, this year’s weather was dry and clear with the sense of autumn in the air.

BGLM volunteers register to work various shifts involving set-up, docents and cleaning up upon closure. Sign-Up Genius online app is used weeks prior to the event. Announcements for signing up encourage individuals to volunteer for the event.

Randi Keppeler is deeply grateful to everyone who volunteered their time to help with docent duties, setup and takedown. Your dedication and generosity made this event possible — we truly couldn’t have done it without them. Every single person came through, and together, we made it happen.

Docents count the number of guests entering the bonsai garden. The number of individuals entering the gate is incredible, numbering 1,800 to more than 2,800. If you missed out of the fun, there is always next year!

Visitors purchase tickets in advance of the event which are limited to 3,500 per night. Funds raised by Autunm Lights Festival are distributed in the form of grants to the themed gardens which includes BGLM.

Afterwards, volunteers spend one day packing up everything and storing the numerous art forms and lights for next year.

Autumn Lights Festival at the Bonsai Garden at Lake Merritt – Volunteers URGENLY Needed!

Autumn Lights Festival at the Bonsai Garden at Lake Merritt – Volunteers URGENLY Needed!

By Randi Keppeler

We especially need volunteers for security of the bonsai garden from 6:00 pm to 11 pm, Thursday, Friday and Saturday.

Just as continuous care for each bonsai tree is critical, so too is caring for the ecosystem that surrounds the tree. This includes not only the soil, water, and nutrients but also the surrounding physical and social infrastructure and the communication of the art of bonsai to new minds. The City of Oakland has wholeheartedly embraced our bonsai clubs and has worked to keep the Bonsai Garden as well as the other Gardens of Lake Merritt thriving. The Autumn Lights Festival, held annually in October, is a fundraiser to help the City with the cost of maintaining the Gardens. The BGLM opens our doors during the Autumn Lights Festival as a way to say Thank You and to give back to the citizens of Oakland. This cycle of receive and give back is part of the greater bonsai ecosystem.

Please join us in this effort. If you have ideas for a lighting display, we would like to work with you to make it happen. If you can spare us some time with preparation, setup, being a docent during the festival, or helping with cleanup on the final day, any and all help is greatly needed and much appreciated. This year the Autumn Lights Festival will be from Thursday October 16th through Saturday October 18th with cleanup on Sunday October 19th.

Landscape lighting that highlights each and every bonsai tree in the garden is installed in the weeks leading up to October’s event. If you have time during the week and some experience with landscape lighting, please let us know. Saturday October 11th and Sunday the 12th we can use help installing rope lights along the walkways. This will keep kids (and parents) on the pathways. Some of the more weather resistant accent lighting displays are set up at this time as well. On Wednesday October 15th and Thursday October 16th during the daytime, the less weather resistant accent lighting is installed. During the Festival itself, we need volunteers to be docents and samurai guards. With over 2000+ visitors each night we need people to keep the bonsai trees safe and to answer visitors’ questions. And finally on Sunday October 19th from 9am to roughly 2pm we take everything down and box it up in preparation for next year.

While we cannot gift families with admission tickets, we can get the Thursday, Friday, and Saturday night docents’ free admission as volunteers. With enough docents, we rotate guard duties so that each person can spend time exploring the rest of the Autumn Lights Festival. We hope that you will join us in having fun and giving back to the community around us.

We greatly appreciate it if you can help us out during any of the following periods:

SETUP:

Saturday October 11th, 9 am to 3 pm

Saturday October 12th, Noon to 3 pm

Wednesday October 15th, 9 am to 3 pm

FESTIVAL GUARD/DOCENT

Thursday October 16th, 6 pm to 11 pm

Friday October 17th, 6 pm to 11 pm
