Seed collection and propagation

Collect seeds between September and November. Collect dry, papery fruits. Check that they contain well developed seeds before making a collection. Shake or strip fruits into a vessel. Remove twigs and other plant material. High seed viability, 80% and 90% from 2 collections. Seeds are non-dormant, high levels of germination were observed with no treatment
