About this species
Arisaema consanguineum is an exotic-looking tuberous perennial, with arum-like flowers, usually striped brown and cream. It is widely available in British nurseries and adds an exotic note to the garden. It is a variable species, which is perhaps unsurprising due to its wide distribution in Asia, and although plants originating from the Himalaya are hardy in southern England, those from Thailand, for example, need glasshouse protection. It is therefore of practical use to know the origin of a plant before purchasing a specimen.
This species was named by Heinrich Wilhelm Schott (1794-1865), Director of the Imperial Gardens at the Schönbrunn Palace in Vienna. He was one of the great experts on the aroid family and produced numerous beautifully illustrated books on the subject.
