Euphorbia hamata is indigenous to the Northern Cape and Namibia. It thrives in the dry, hot conditions of the open veld found there. It is cultivated widely, also in the USA, Europe and other parts of the world for its quite special flowers and branched spiny stems. This species also resembles Euphorbia peltigera.
Traditional headgear and even some modern fashion designs from over the world present several items that may have been inspired by these flowers cupped in their creamy-white bracts.
