Prasophyllum crassum

Prasophyllum crassum is a small leek orchid native to south-east South Australia, growing from an underground tuber and producing a single tube-shaped leaf and a spike of greenish, pinkish-brown flowers. It usually appears after fire and grows in low, winter-wet heath areas, so it is best cared for as a native plant in its natural habitat or in a cool, moist, native bed.

About

Prasophyllum crassum is a species of orchid endemic to South Australia. It has a single tube-shaped leaf and up to fifteen greenish and pinkish-brown flowers with a whitish labellum. It is a recently described plant, previously included with P. fitzgeraldii, but distinguished from that species by its smaller number of smaller, less colourful flowers and different labellum shape. It grows in the south-east of the state and usually only appears after fire.

Where it grows

This leek orchid mostly grows in low lying, winter wet areas in the Big Heath Conservation Park and between Kingston, Mundulla and Frances. It often grows with other species of leek orchid.
