Upcoming Meetings & Events:

May 8th:
Peter Lin – Charming Miniature Cattleyas

Peter started growing orchids over 35 years ago, but then stopped due to school and starting a career. It wasn’t until about 14 years ago that the orchid “bug” came back, and he is now heavily involved once again! He is an accredited judge with the American Orchid Society, and a hybridizer of mini-catts. He enjoys meeting with other orchid enthusiasts and can often be found at various orchid shows and societies around the country.

Peter LinDue to limited growing space, Peter likes to specialize in miniature orchids, both species and hybrids, and has received numerous AOS awards. His interests in orchids include Dendrobiums, Angraecoids, and Neofinetias. He is also known as “Mr Sophronitis” as he has a passion for growing and collecting them. He maintains a collection of a thousand or more orchids at his home in Southern California in 3 small greenhouses, outdoors, as well as an offsite greenhouse.

Peter will give us a fast-paced PowerPoint presentation on these charming Cattleya orchids. The journey will begin with a review of the miniature species, early hybrids, and then to some of the relevant hybrids of today. We will also review how to grow these wonderful plants. Peter will also be supplying the opportunity table.
