Distribution

Merwilla plumbea is found in the eastern part of South Africa, in Eswatini and Lesotho. [2]

Habitat

Merwilla plumbea is found on rocky, well-drained slopes at altitudes between 300-2500 metres. [2]

Ecology

Mature individuals are thought to live, on average, for 25 years. [2]

Conservation status

Merwilla plumbea has been assessed as near threatened due to a 25% decline in the local population from intensive poaching of the bulbs in the wild. In 2006, 1 851 580 bulbs in the Warwick Muti Market and 235 872 bulbs were sold in the Faraday Muti Market. [2]
