Cultivation Details

HabitPerennial Climber
Growth—

Easily grown in a fertile well-drained soil in a sunny position or light shade[2]. Prefers a rich light soil[3]. Plants produce tubercles (small tubers that are formed in the leaf axils of the stems), and can be propagated by this means[PFAF]. A climbing plant that supports itself by twining around the branches of other plants[4]. Dioecious. Both male and female forms must be grown if seed is required.

Propagation

Seed - sow early spring to mid spring in a sunny position in a warm greenhouse and only just cover. It germinates in 1 - 3 weeks at 20°c[5]. Prick out the seedlings as soon as they are large enough to handle and grow on in a greenhouse for their first year. Plant out in late spring as the plant comes into new growth. Basal stem cuttings in the summer[6]. Division in the dormant season, never when in growth[3]. The plant will often produce a number of shoots, the top 5 - 10 cm of the root below each shoot can be potted up to form a new plant whilst the lower part of the root can possibly be eaten[PFAF]. Tubercles (baby tubers) are formed in the leaf axils. These are harvested in late summer and early autumn when about the size of a pea and coming away easily from the plant. They should be potted up immediately in individual pots in a greenhouse or cold frame. Plant out in early summer when in active growth[PFAF].
