The Rocky Mountain Bonsai Society

WELCOME

The word “Bon-sai” (often misspelled as bonzai or banzai) is a Japanese term which, literally translated, means “planted in a container”. This art form is derived from an ancient Chinese horticultural practice, part of which was then redeveloped under the influence of Japanese Zen Buddhism.

The Rocky Mountain Bonsai Society (RMBS) is a Denver Botanic Gardens affiliated Plant Society, a member society of the American Bonsai Society and Bonsai Clubs International.  RMBS was started in 1969 and has a proud lineage to the Denver Bonsai Club started by seven Japanese men in 1945.  Please see our history page for more information.
 
Bonsai are kept small by careful management of the plant’s growth while providing for its horticultural requirements.  Every species of plant has its own special needs.  Colorado's dry climate, cold winters and high altitude differs from what one finds in Bonsai books, Rocky Mountain Bonsai Society (RMBS) can help you succeed with bonsai. Our members have been teaching bonsai and developing private bonsai collections since 1969.  We work with Japanese bonsai species, cold hardy plants from the Rockies and even tropicals.
 
RMBS presents educational programs to members on some aspect of bonsai at 7:00PM on the first Tuesday of each month, except in December when its holds the annual holiday party.  Unless otherwise noted (on the website) these meetings are held at the Denver Botanic Gardens’ Plant Society Building; 1007 York Street, Denver, CO  80206.  
 
Eight months of the year members get together on the last Saturday of the month to work together on their individual trees and share their experiences.  Since 1973, RMBS has hosted a public bonsai exhibition at the Denver Botanic Gardens.  Members exhibit their best bonsai trees and Suiseki (Viewing Stones). ​In 2019 we will be hosting the 50th Annual Bonsai and Suiskei Show.

SHORT PROGRAM - Hoop Houses and GreenHouses With Knowledgeable RMBS Members
A hoop house is a type of greenhouse that’s built using a hooping or bending system. A hoop house can be as small as a cold frame structure hooped over a few garden rows in a backyard, or as big as a full sized, fully functional, commercial greenhouse.A hoop house is a rounded, gently bending structure attached to a frame, rather than the old-fashioned solid glass or Plexiglas structure.  The advantages of a hoop house are many; they are easy to assemble, durable, and can be built in any number of sizes.
MAIN PROGRAM - Bonsai Ecology  With Mike Britten 
Ecology is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography and Earth science. Ecology includes the study of interactions organisms have with each other, other organisms, and with abiotic components of their environment.
Ecology addresses the full scale of life, from tiny bacteria to processes that span the entire planet. Ecologists study many diverse and complex relations among species, such as predation and pollination. The diversity of life is organized into different habitats, from terrestrial (middle) to aquatic ecosystems.
