Vascular – Exotic
Naturalised (garden escape). Recorded once in 1986 from a gully system in Hamilton City (WAIK 6157)
Easily grown from tubers and spreadign readily from these in cultivated sites. The sole naturalisation known probably came from discarded garden waste containing tubers of this species. Commonly cultivated in many parts of New Zealand.
arisarum: Possible from the Greek arista ‘bristle’ or ‘awn’ and arum, to which the genus is allied, referring to spathe of flower having a spike.
