“This month the Denver Orchid Society has the pleasure of hosting Peter T Lin from Diamond Orchids of S. California. Peter will be presenting his talk on:  The 3 A’s of the Orchid World:  Angraecum, Aerangis and Aeranthes.  This fast-paced PowerPoint presentation will showcase 3 of the main genera in the Angraecoid family of Orchids, as well as some of the lesser genera.  Peter started growing orchids over 35 years ago and is an accredited judge with the American Orchid Society and a hybridizer of mini-catts. Peter likes to specialize in miniature orchids, both species and hybrids, and has received numerous AOS awards.  His other interests in orchids include Dendrobiums, Angraecoids, and Neofinetias.  He maintains a collection of a thousand or more orchids at his home in Southern California in 3 small greenhouses, as well as in the house under fluorescent lights.

Peter will be accepting orders that he will ship to members.  All orders qualify for a 10% discount.  You can review his catalog on his website:
