They form at the top of wiry stalks over 30 cm long. They start as an olive green colour, but dry to a light brown. The seed itself is much like a parasol in appearance, and is around 5mm across. Germination is slow and unreliable and requires warm temperatures.Leaves are smooth and of a bright, light green. Plants like sunny positions and generally grow in sunny, open mallee forests.
