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 December meeting will be presented by Carol Klonowski . The title of his talk will be “Orchids of South Africa”.

Carol Klonowski has been growing orchids since the 1980’s when a friend in Berkeley, California, gave her a Cattleya and it bloomed out with three big, dark lavender flowers and an intoxicating fragrance. She built an entire greenhouse in her backyard to accommodate the precious plant, which only led her to buy more orchids. Then another friend gave her a gift membership to the Orchid Society of California, and it’s been a serious passion ever since. She is an accredited judge with the American Orchid Society, and current President of the Orchid Society of California.
Her presentation on the Orchids of South Africa will take everyone on a tour of the orchid growing areas of this fascinating part of Africa and the world.  Long known as one of the gardens hot-spots of the planet, South Africa has a diverse and fascinating number of habitats and climates that provide a robust setting for flora and fauna of all types.

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