Bonsai Conventions & Symposia
THE  CONVENTIONS  &  SYMPOSIA


A typical convention might include demonstrations (identified below as "demo"), workshops (identified below as "work"), lectures (identified below as "lect"), presentations (identified below as "present"), exhibition, banquet, awards, silent auction, vendor area and bazaar, business meeting, tours of local enthusiasts' collections, tours of local cultural interest.

This is by no means an exhaustive list.
 There have been many other congregations, often held at the same location year after year. 
Here we have what have been among the largest and most internationally attended gatherings
at differing sites.
If you are aware of missing information in this listing or feel that another group's conventions
should be included here, please e-mail rjb@phoenixbonsai.com with as many details as possible.

This list was compiled from material found in the assorted specialty magazines (advertisements and articles before and after the conventions), convention brochures, books, and web sites.  Special thanks to Solita D. Tafur Rosade (FELAB), Joy Williams and Kath Hughes (FoBBS), and Kym James (AABC Ltd.) for their valuable input and corrections.

Also, profound thanks go out to all the unnamed committee chairpersons and behind-the-scenes helpers
without whom none of these educating and entertaining functions would have been possible.
