Flowers in Summer (Nov to Mar), favours woodland, open and heathy forest.

Appears to have a strong dependence on eucalypts and unlikely to be found in forests without eucalypts being present. It is possible that this orchid is parasitic on the fungus normally associated with the roots of the eucalypt.

Pollination is reported to be by small bees and wasps.

There are four species shown here - Rosy Hyacinth (D. roseum), Spotted Hyacinth (D. pardalinum), White Hyacinth (growing in the Dandenong Ranges) and Blotched Hyacinth (D. variegatum).
