Rare and Endangered Species
Plant Threat Level: 

Lachenalia mathewsii is an endangered plant and was considered extinct from 1943 until 1983, when it was rediscovered. The genus Lachenalia is endemic to southern Africa and is the largest genus in the Hyacinth family (Hyacinthaceae). Unfortunately, most of the natural habitat has been converted to agricultural use and, as a result, it grows naturally in only one area. Luckily, Kirstenbosch National Botanic Garden in Capetown, South Africa, has worked to make plants and seeds available so that today Lachenalia mathewsii is grown worldwide.
