Description
The species is a tough perennial plant which grows in flat, woody mats in sand and gravel substrates. It has small, fuzzy gray leaves (under 2.5 centimetres (1 in) long)[1] which are scoop-shaped due to their rolled edges.
In early summer,[1] short stalks emerge from the mat with inflorescences of greenish-yellow and whitish rounded clusters of flowers. These redden with age[1] and hang backwards over the edge of the involucre. The species is dioecious.[2] Some of the flowers are bisexual and up to 1 cm wide each, and some are only staminate and much smaller.[citation needed]
