About

Cullen pallidum, the woolly scurf-pea, is a species of Cullen, a short-lived perennial herb, considered native and found in all states of mainland Australia. It is considered rare in Victoria and common in all other states. Its common names include: woolly scurf-pea, woolly psoralea, Bullamon lucerne, and white scurf-pea. Found primarily in habitats characterized by moving sand dunes, this species often has lower stems partially buried beneath the sand.

How to grow it

Seeds can be collected during September to April, by running your hand along the spikes of the fruits when they are mature, fat pods turning black with a brown seed inside. Leave pods to dry for 1 to 2 weeks, then rub together to dislodge the seeds. This species has a period of physical dormancy, which can be overcome by nicking or soaking the seed coat to germinate the seed. Several case studies are testing the viability of using Cullen sp., including C. pallidum, as perennial pasture legumes for cropping in the low-rainfall wheatbelt of Western Australia due to their adaptiveness.

Where it grows

Found primarily in habitats characterized by moving sand dunes, this species often has lower stems partially buried beneath the sand, although this does not reflect a specific growth habit. C. pallidum is listed as threatened and protected under Flora and Fauna Guarantee Act 1988 (FFG) and considered endangered in the Advisory List of Rare or Threatened Plants in Victoria, which states the species is at risk if current land uses and other factors continue to operate, of disappearing from the state.
