General Notes

Plants spread by stout rhizomes and may be invasive.Division of rhizomes during the autumn and early winter is the quickest method of propagation. Divided plants can either be planted directly into their final growing position or potted up and grown on for a year. Remove half of the leaf area to reduce transpiration and water loss and aid establishment. Clean fermented pulp from seeds by soaking in a sugary solution and sow immediately. Smoke treatment has increased results for some species. Soaking seed in soapy water (velvet) or a light scarification with sandpaper have also been recommended. Temp. may be critical in germination i.e. not above 18oC - Andrew Stevenson. Used in traditional Palawa basket weaving. (Ref. Tasmanian Aboriginal Baskets). Also used in modern basket weaving. Suitable below powerlines.

Seed Information

Seed Collection

Seed is black and shiny, and contained in a blue-purple oval-shaped berry. fleshy fruits turn soft when mature. collect into plastic bags as paper bags become soggy. allow to ferment for several weeks

Seed Treatment Method

Hot water

Seed Storage Life

6-12 months

Viable Seeds Per Gram

160

Seed Treatment Notes

Hot water treatment of seed before sowing has been successful. 1 or 2 drops of detergent will help break surface tension and allow water penetration. Autumn sowing is best. See General notes re. fermentation*

Germination Time

2 weeks to several months

Suitable for Direct Seeding

Cuttings

Propagation by Division N.B. Transplant only from nearby to avoid disease.

Yes

Cutting Notes

Relatively easy by division. Division of rhizomes during the autumn and early winter is the quickest method of propagation. Divided plants can either be planted directly into their final growing position or potted up and grown on for a year. Remove half of the leaf area to reduce transpiration and water loss and aid establishment.
