Our annual show and sale is held in May at the Arboretum's Ayres Hall and is open to the public. In addition to plants and flowers, you can see floral arrangements and photography focused on epiphyllums.

Benefits of membership include access to the quarterly Bulletin, the Society's publication that includes seasonal growing tips and useful articles. Members enjoy a 1/3 off discount on the Registry of Hybrids and Species. Every year the Society publishes an addendum to the Registry which is made available to all current members. We also participate in Cactus and Succulent Society of America events as an affiliate society. Hybridizers who join the ESA enjoy a 50% discount on registration of their new named varieties. Most importantly, your membership allows us to pursue our mission of promoting public awareness about the care and cultivation of epiphyllums and other epiphytic cactus species.

Unfortunately, the cost of postage alone to send a copy of the Registry overseas is more than $26.00 (it cost $27.85 to mail to New Zealand) to which we need to factor in the price of packing materials. We apologize to our overseas friends for how much they need to pay to get a printed copy of the Directory, however, we have no control over postal rates.
