Merwilla plumbea, also known as the blue squill, is a threatened bulb-forming perennial herb in the small genus Merwilla endemic to the Drakensberg.

[1][2] Merwilla plumbea is found in the eastern part of South Africa, in Eswatini and Lesotho.

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

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

[2] 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.
