Distinctive Features

Leaves crowded towards the base of the plant. Leaves appear grey, covered with cobweb-like hairs, especially underneath. Seed of this species becomes jelly-like on wetting and sticks it to the soil to aid germination, an adaptation for dry environments.

Biology

Perennial. Well-drained soils. Can stay green all year round, or die off in dry seasons and re-sprout from a rootstock. Threats include grazing by rabbits and livestock, as well as changes to fire patterns. Seeds dispersed by wind. Long-lived.
