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 last Saturday of the month at various members’ homes / bonsai gardens.  Since 1973, on the Fathers’ Day weekend, 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.
