Arisaema candidissimum AGM

This plant, a member of the arum family, originated in China. Its common name is white-spathed jack in the pulpit and it is a large cousin of Arisarum probiscidem which is also in the garden. Its leaves come after the white, hooded spathes. Hidden deep inside the spathes are tiny blue flowers clustered around the base of the club-like spadix (spike).

Cultivation: it grows best in acid or neutral soil in full sun or part shade. Avoid the tubers drying out in winter and in cold areas it may need protection. Propagate by seed or offsets removed in late summer.
