Zieria aspalathoides is a heath-like shrub which grows to a height of between with branches that are ridged and scaly or hairy, at least when young. The leaves are composed of three linear to lance-shaped leaflets long and wide. The leaves have a stalk less than long and are arranged in opposite pairs, so that there appears to be a whorl of six simple leaves. The edges of the leaflets are rolled under and the upper surface is a darker green than the lower one. The flowers are pale to deep pink and are arranged in groups of mostly three, the groups usually longer than the leaves. The
sepals are triangular, about long and usually smooth but hairy. The four petals are long, overlap at the edges and are covered with short, soft hairs and there are four
stamens. Flowering occurs from late winter to early summer and is followed by the fruit which is a mostly
glabrous follicle containing black seeds. ==Taxonomy and naming==
