Members are encouraged to bring their flowering Orchids for display on the show table at our regular meetings. Attendees will be asked to vote for the Orchid they like best. Exhibitors may be coaxed into divulging the "secrets" they have for growing Orchids.

Many of our speakers are also Orchid growers and bring plants to sell. The number of plants for sale will be limited so get there early for the largest selection.

Please check this calendar often for updates. If a meeting is cancelled for some reason, we will post that here and send out email notices to our members.
