Seed collection and propagation
Collect seeds between September and February. 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 100% on 1% w/v agar, 8/16 dark/light, 20°C. See http://data.kew.org/sid
