The species varies from 0.2 - 2.5m but most forms are under 50cm and compact or spreading with grey - green foliage, resembling lavender, which gives the species its name. 'Victor Harbor', however, grows to 1m and has dark green leaves.

The flowers are usually red or pink, although cream varieties exist, and are born profusely and conspicuously as spider like clusters in winter and spring. They are nectar rich and attractive to honey eaters.

The plant grows in full sun to dappled shade on all soil types which must be well drained or dry. It is drought and moderately frost tolerant and tolerates a wide range of pH.
