Growing to 2.5 m (8.2 ft), it is hardy only in milder areas which do not suffer prolonged frosts, where tubers may be left in the ground throughout the year, and protected with a mulch in the dormant season. Otherwise tubers must be lifted and stored over winter. They begin to sprout in spring, but must be protected until all danger of frost has passed. Propagation is by seed or cuttings in spring.[3]
