Seed collection and propagation
Collect seeds between February and April. Pick the seeds from the cluster with your fingers, those turning a pale colour and come away easily from the stalk. Place the seeds in a tray and leave to dry for 1 to 2 weeks. No further cleaning is required. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
