The Rocky Mountain Bonsai Society

The Rocky Mountain Bonsai Society (RMBS) was founded in 1975 and has a proud lineage to the Denver Bonsai Club which was founded in 1945.  RMBS is a Denver Botanic Gardens (DBG) affiliated plant society and a society member of both the American Bonsai Society and Bonsai Clubs International.  For more information about RMBS’ history please refer to the History of the Rocky Mountain Bonsai Society.
Monthly meetings are typically held on the first Tuesday of each month from 7:00 thru 9:00 pm and held at the Denver Botanic Gardens’ Plant Society Building.  All the monthly meetings are open to the public. Nine months of the year, members meet for a Saturday workshop.  Most of the workshops are either at the Bill Hosokawa Bonsai Pavilion, or the Plant Society Building. Please check this link for more information on Bill Hosokawa's life and his numerous contributions. 
Annually, RMBS has a Bonsai Show at the Denver Botanic Gardens to display some of its member’s best bonsai trees for the public’s enjoyment.
