Welcome to the rocky mountain bonsai society
In-person RMBS gatherings will resume periodically starting in July 2021. At this time, the schedule is month-to-month. Please check the schedule of events on this site for in-person offerings. All monthly meetings will remain available on the Zoom platform as well.
Trident Maple (acer buergerianum)
We are the premier bonsai society in the Rocky Mountain region, based in Denver, CO. In association with the Denver Botanic Gardens, we curate the bonsai collection at the Bill Hosokawa Bonsai Pavilion which includes many specimens collected from, and indigenous to the Colorado area. Our mission is to advance the appreciation of, inspire interest in, and educate about the art of bonsai. Over half a century has seen RMBS members create and cultivate exceptional private collections of bonsai for the world to enjoy.
We are an inclusive community of bonsai practitioners representing every skill level. We focus on education, bonsai cultivation, and advancing interest in bonsai and related arts. RMBS started in 1969 and has proud lineage to the original Denver Bonsai Club founded by seven Japanese Americans in 1945 (see history tab). We are a Plant Society affiliate of the Denver Botanic Gardens and a member of Bonsai Clubs International and the American Bonsai Society.
Bonsai remain small through careful management of the plant’s growth in a containerized environment while optimizing its horticultural requirements. Every species of bonsai has unique needs. Given Colorado's dry climate, frigid winters, and high altitude, bonsai refinement often requires knowledge and techniques that differ from traditional teaching found online and at your local library. We can help you succeed in cultivating a wide range of bonsai in the Rocky Mountain region (everything from native conifers to flowering tropical trees). Our members have been teaching bonsai and developing private collections for over half a century and are ready to help you along your journey. Each year, RMBS invites numerous internationally renowned bonsai professionals to provide demonstrations and workshops for our members to advance in their practice.
Korean Hornbeam (carpinus coreana)

Please join us for our monthly meetings which are free and open to the public. These educational programs address the art of bonsai and related topics. They run from 7-9pm on the first Tuesday of each month (except in December when RMBS holds the annual holiday party). Unless otherwise noted (see events tab), these meetings are held at the Denver Botanic Gardens; 1007 York Street, Denver, CO 80206.
Look for additional RMBS offerings for the 2021/2022 season in Colorado Springs. Please continue to visit this site for periodic updates.
Since 1973, RMBS has hosted a public bonsai exhibition at the Denver Botanic Gardens. Members exhibit exceptional bonsai and suiseki (viewing stones) compositions from their personal collections. On September 4th-5th 2021, we will be hosting the 52nd Annual Bonsai Exhibition which promises to be our most inspiring to date!
