Description

edit

Leptospermum squarrosum is an erect shrub of variable habit, growing to a height of less than 1 m (3 ft 3 in) to 4 m (13 ft) or more and has thin, firm bark. Young stem are silky-hairy at first, soon glabrous. The leaves are variable but mostly broadly lance-shaped to elliptical, 5–15 mm (0.20–0.59 in) long and 2–5 mm (0.079–0.197 in) wide with a sharply-pointed tip and tapering to a short petiole. The flowers are white or pink, mostly 10–20 mm (0.39–0.79 in) wide and arranged singly on short side shoots. The floral cup is sessile, 2.5–4 mm (0.098–0.157 in) long and glabrous. The sepals are also glabrous, 2–3 mm (0.079–0.118 in) long, the five petals 3–7 mm (0.12–0.28 in) long and the stamens 3–4 mm (0.12–0.16 in) long. Flowering mostly occurs from March to April and the fruit is a capsule mostly 8–12 mm (0.31–0.47 in) wide that remain on the plant at maturity.[2][3][4][5]

Taxonomy

edit

Leptospermum squarrosum was first formally described in 1788 by Joseph Gaertner in his book De Fructibus et Seminibus Plantarum from specimens collected by Joseph Banks.[6][7]

Distribution and habitat

edit

Peach blossom tea-tree gows in shrubland on sandstone soils in coastal areas and nearby tablelands of New South Wales, but especially in the Sydney region.[2][3]

Use in horticulture

edit

This tea-tree is a hardy shrub that grows best in a sunny situation in well-drained soil, but is salt-resistant and tolerates exposed positions.[4]
