Syzygium smithii aka Lilly Pilly

Syzygium smithii, or lilly pilly, is an evergreen tree. It belongs to the myrtle family, Myrtaceae. Its native range follows eastern Australia south to Victoria. It grows in Queensland and New South Wales too. The name Acmena smithii remains in use as a synonym. In the wild, it grows in rainforest beside streams and rivers. Its range extends from sea level into upland sites.

The tree forms a dense crown that keeps its leaves year-round. The reference lists a height of about 49 feet [15 metres]. Warm, sheltered sites can support much taller trees. These may reach 66–98 feet [20–30 metres]. Exposed coastal plants can stay small and take a shrub form. The trunk is often short and has an uneven shape. Larger trunks measure about 1–2 feet [0.3–0.6 metres] across.

Its foliage, flowers, and fruit give it value in gardens. Bees and other insects pollinate the flowers. Large clusters of small berries follow, with pink to whitish skins. Each berry measures about 0.03–0.05 feet [0.01–0.015 metres] across. The fruit draws birds and also provides food for people. People eat it fresh or cook it for preserves and drinks. Its taste is mild and watery, rather than rich. The source lists no known hazards, but gives no detailed safety assessment.

Lilly pilly suits warm subtropical and tropical conditions. Older trees grow in full sun or beneath light, broken shade. Young plants need shelter from strong sun. It accepts most soil types where excess water drains away. It prefers acidic soil, with a pH of 5–6. The reported tolerance extends from pH 4.5 to 6.5. Frost limits its use in colder gardens. Temperatures of 30°F [−1°C] can kill new shoots. Cold of 23°F [−5°C] or below can kill the plant.

Gardeners grow this tree for its leaves, flowers, and bird-attracting fruit. It also serves as a street tree. People harvest wild trees for fruit and usable timber. The wood has a fine grain and moderate strength. Builders use suitable pieces for construction, indoor fittings, and frames. It withstands weather better than contact with the ground. Seeds lose viability soon, so sowing fresh seed matters. Reports differ on how fast and reliably seeds sprout. Cuttings from firm growth made that season offer another way to raise plants.
