Silky Teatree derives its name from the silky hairs which grow on the calyx (outer floral parts). It is a low-growing shrub from shin high up to a metre in height along the cliff tops where it is restricted to Coastal Heathland.
Leaves are small, pointed, lanceolate to narrowly obovate with the margins upturned (concave) and sometimes minutely serrate (denticulate).
Flowers are 5 petaled, usually white but occasionally with a pink tinge and produced en masse. Flowering is from late winter to late spring.
Fruits are spherical and mostly deciduous (falling off at maturity) although occasionally this is a slow process taking many months.
Many insects including beneficial predatory Hover Flies are attracted to the flower display.

Coast Teatree (Leptospermum laevigatum) which has been introduced into areas where Heath Teatree grows has created a vigorous hybrid (L. laevigatum x L. myrsinoides) that grows very densely and is capable of smothering all surrounding heath vegetation. Ongoing work to remove it is critical to maintain coastal heath biodiversity.
