Plant Propagation

Seed - we have no information for this species but suggest sowing the seed as soon as it is ripe in a pot submerged in water. The seed is likely to have a short viability if allowed to become dry. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division is easy at almost any time in the growing season[200].
