Seed collection and propagation

Collect seeds between November and May. Collect seeds when fruits are brown and papery. Check inside several fruits for the presence of well-developed seed before making a collection. Strip or shake fruiting branches into a container. Remove twigs and other plant material. Germination may be inhibited by the fruiting perianth as levels increased after its partial removal.
