The Rocky Mountain Bonsai Society



The Rocky Mountain Bonsai Society (RMBS) is a plant society affiliated with the Denver Botanic Gardens. It was founded in 1975 with a lineage to the Denver Bonsai Club founded in 1945.   Please go to the website’s history tab for more information about the society’s unique past.

RMBS monthly meetings are typically on the first Tuesday of each month starting at 7:00 p.m. and held at the Denver Botanic Gardens’ Plant Society Building.  Non-Members are welcome at the monthly meetings.  Nine months of the year, members meet on the third Saturday of the month at various members’ homes / bonsai gardens.  Since 1973, RMBS has held a 3 day bonsai exhibition at the Denver Botanic Gardens to display some of its member’s best bonsai trees for the public’s enjoyment.

 * It is Rocky Mountain Bonsai Society's policy and practice not to collect native trees (Yamadori) without a permit from the U.S. Forest Service, The Bureau of Land Management or permission from a Land Owner.   

Takayama Park Clean-Up

Denver Botanic Gardens
3875 Cherry Creek N Drive; Denver, CO  80209

What a great way to welcome spring to our beautiful city and state, which is by volunteering for the most worthwhile semi-annual Takayama Park clean-up.  Not only is it fun, but you will learn the correct way to trim and maintain the shape of the Ponderosa Pines located at this park.
Volunteers from the Denver Takayama Sister City Committee and the Japan America Society of Colorado will be working side by side with RMBS members.  
Takayama Park was dedicated by Mayor Tom Currigan in 1967 along with several distinguished Americans of Japanese heritage.  Character trees were collected by members from the Denver Bonsai Club, one of whom was our dear friend Tom Taggart.  This park was very important to Tom, as he was to us.
Celebrate Spring with us.  Bring some gloves and gardening clippers.  Refreshments will be provided.
