"E Namibia Semper Aliquid Novi - New Plants from an Old Place"

Presented by Tim Harvey

Tim started growing cacti (almost exclusively) in England over 30 years ago. In the early 90s he moved across the pond to North America and in 1994 settled in California. Since then his interests had changed, focusing on the "other succulents", especially pachycaul and xerophytic trees. Tim also grows quite a few Aloes and geophytes. He has a Ph. D. in Biochemistry and having escaped the Biotechnology Industry with his morals intact, he now spends his time trying to get his backyard nursery to be more productive.

Against the spectacular backdrop that is Namibia, the program will cover the summer rainfall area (with a few diversions), with emphasis on the 'big' plants e.g. Cyphostemma and Commiphora. The effects of various factors, natural and otherwise, on the plants from year to year will be illustrated and a number of little-known or undescribed species discussed. Finally, the horticultural potential of Namibian plants will be illustrated.

Please don't miss this great presentation about an incredible area of the world. This is a presentation everyone should see.

FREE PLANT GIVEWAY

This month's free plants are Euphorbia resinifera and E. coerulescens , recommended for pot culture or under filtered light in the ground. Both are hardy to the mid or high 20's without protection, tree cover will provide some additional frost protection. Euphorbia is a genus of plants belonging to the family Euphorbiaceae. Consisting of about 2160 species, Euphorbia is one of the most diverse genera in the plant kingdom. Members of the family and genus are sometimes referred to as Spurges. The genus is primarily found in the tropical and subtropical regions of Africa and the Americas, but also in temperate zones worldwide. Succulent species originate mostly from Africa, the Americas and Madagascar. Euphorbia are annual or perennial herbs, woody shrubs or trees with a caustic, poisonous milky sap (latex) that will cause irritation to the eyes and mucous membranes. The roots are fine or thick and fleshy or tuberous. Many species are more or less succulent, thorny or unarmed. The main stem and mostly also the side arms of the succulent species are thick and fleshy, 15-91 cm (6-36 inches) tall. The deciduous leaves are opposite, alternate or in whorls. In succulent species the leaves are mostly small and short-lived.
