Seed Information

Seed Treatment Notes

Orchid seeds are very minute yellow, brown or blackish dust-like particles. Orchid seeds are produced within a capsule that splits at maturity and releases thousands to millions of seeds. Dispersed by wind and water and only germinate following infection of the embryo by a suitable mycorrhizal fungus. Very few seeds become mature plants. For more information see Jones, Wapstra, Tonelli, Harris (1999): The Orchids of Tasmania.
