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 on a Saturday of the month at DBG’s Bill Hosokawa Bonsai Pavilion.
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.
