Oxalis

Oxalis is a huge genus of about 270 species within 6 subgenera of the family Oxalidaceae found in many parts of the world, but with a large number found in South Africa and South America. Oxalis was the subject of the PBS list topic of the week in November 2003. To read the introduction by Robin Attrill for this topic view this link. Another post with a lot of good background information on this subject was in this list post from David Victor. For the most recent comprehensive information about the names of the species see Clifton, 2004 in References.

The genus Oxalis has a reputation as a weed, and a few species really are weeds in parts of the world. But most are not. The late Michael Vassar, Curator of Floristic Gardens at the Huntington Botanical Garden, played a big role in popularizing Oxalis bulb culture by donating several South African collections to charity fund-raisers in the late 1990s. Many of his selections turned out to be relatively easy to grow, but not invasive in the garden. Download a list of his complete collection here.

Photos 1-2 below taken by Bill Dijk are a collection of Oxalis species painted by botanical artist Zoë Carter from Nelson, New Zealand. Bill has kindly added the names in the second photo. Photos 3-5 show flowers and leaves scanned by Ron Vanderhoff. He also has added the names of the leaves, but the limits of the wiki has meant the file had to be reduced. These photos show the great number of flowers that can be in bloom at the same time in his collection and the great diversity of leaf types of this genus. Photo 6 by Nhu Nguyen shows a bouquet of various species.
