About

Arisaema candidissimum is a species of flowering plant in the arum family (Araceae), originating in western China (Tibet, Sichuan, Yunnan). Various English names have been given to the species, including Chinese cobra lily and Chinese jack-in-the-pulpit. The Chinese name is 白苞南星 (bai bao nan xing).

How to grow it

Brian Mathew considers it by far the best species of Arisaema for British gardens and recommends growing it in a warm, sunny place, although it should not be too dry in summer. A list produced for the International Aroid Society says it is hardy to −20 °F (−30 °C), USDA Zone 4b. Two clones were originally introduced into cultivation by Forrest, one pale pink, the other pure white. Forms introduced later by Chinese suppliers include plants with darker, reddish-pink stripes.

This plant has gained the Royal Horticultural Society's Award of Garden Merit.
