The Cactus and Succulent Society of Massachusetts (www.cssma.org) will present a program on Succulent Pelargoniums on Saturday, October 17, from 1:00 – 4:00 pm, at Tower Hill Botanic Garden, 11 French Drive in Boylston. The program will be led by Dr. Matt Opel, of the Department of Ecology and Evolutionary biology at the University of Connecticut. While Dr. Opel’s research focuses on micromorphology and anatomy of Conophytum leaves, he also enjoys Japanese animation, gardening, and hiking, so the program should prove to be quite interesting.
