Next Meeting:

Aloe hybridization in South Africa: The work of Andy de Wet, Leo Thamm, and the legacy of Arthur Koeleman.

By Jason Sampson
Tuesday, April 15, 7:00 pm

Location: Auditorium in the San Francisco County Fair Building, 9th Ave and Lincoln Way, San Francisco MAP

Jason Sampson will present the aloe hybrids of Andy de Wet and Leo Thamm, two well-known South African Aloe hybridizers whose spectacular introductions have been making waves in horticultural circles both in South Africa and more recently here in California, as their hybrids have begun to make their way into horticulture here. Both were influenced by the earlier work of Arthur Koeleman.

Jason Sampson is the Curator of the Manie van der Schijff Botanical Garden, a division of the Plant Sciences Department at the University of Pretoria. He is currently in charge of the ongoing green wall project of the new Plant Sciences Complex at the University's Hatfield Campus, an exciting and ground-breaking construction that combines horticulture, green building design, and habitat creation. He has just completed a larger and more ambitious project involving the installation of a rainwater harvesting system, which is beginning to attract a large amount of national and international attention as it is a first in South Africa. Jason also guest lectures for the Landscape Architecture Department. He believes passionately in the capacity of natural systems to better quality of life and that sustainable development depends on the effective management and conservation of biodiversity.

The featured grower will be Marilyn Mangle.
