Euphorbia hamata is indigenous to the Northern Cape and Namibia. It thrives in the dry, hot conditions of the open veld found there.
The species resembles E. peltigera.
This plant is cultivated widely, also in the USA, Europe and other parts of the world for its quite special flowers and branched, contorted stems.
Traditional headgear and even some modern millinery designs include shapes resembling these flowers. Who knows where the muses hide?
