Seed Information

Seed Collection

Very difficult to grow from seed. Some species retain seed on the plant for several years. Cut the whole seed head with secateurs and allow to dry. Beat against a hard surface to extract, being careful of sharp foliage.

Seed Treatment Method

Smoke Smoke treatment improves germination in some species. Smokey products, e.g. smokey vermiculite, can be purchased and applied to the sown seed, or sown seeds can be treated directly with smoke from a source such as a drum with a fire and hose.

Seed Treatment Notes

Seed is slow to germinate and may have low viability. Seed is reputed to germinate very slowly if sown in dark and moist conditions. A combined heat-smoke treatment may be worth trying, possibly with older seed.

Cutting & Division Information

Can be propagated by division over the winter months, but plants are slow to re-establish.
