Calendar of Events

Interested members of the general public are welcome to attend up to two meetings before deciding whether to join the Denver Orchid Society. We are currently meeting by Zoom only, and you are free to lurk there without audio or video to see what we’re about (you can use audio and video if you want) . To be sent a Zoom link to check us out just send a request to Jerry D’Amato at . We hope you will join us.


The October meeting will be presented by Dr. Kristen Uthus. The title of his talk will be “Masdevallias and Draculas: Not as Scary as You Think”.

This subset of the Pleurothallid Alliance has long been beloved by orchid growers; how-
ever, I hear the refrain, “I can’t grow them” way too often. You would be surprised at the

success the average grower can have under “normal” growing conditions. I talk about
what makes these two genera so attractive, how to grow them in intermediate to warm
conditions, and some great species to try if you are still hesitant.

We are still meeting remotely by Zoom, so watch your email for connect information.
