Description

edit

Leptospermum sphaerocarpum is a shrub that typically grows to a height of 2 m (6 ft 7 in) with thin, firm bark and young stems usually covered with soft hairs. It has broad to narrow elliptical leaves 5–10 mm (0.20–0.39 in) long and 2–5 mm (0.079–0.197 in) wide with a sharply-pointed tip and tapering at the base to a short, thick petiole. The flowers are greenish white or pink, mostly 15–20 mm (0.59–0.79 in) wide and arranged singly on short side shoots. There are many reddish brown bracts at the base of the flower bud but which fall off long before the flower opens. The floral cup is densely silky-hairy, 3.5–5 mm (0.14–0.20 in) long and the sepals broadly egg-shaped, about 3.5–5 mm (0.14–0.20 in) long. The petals are 5–7 mm (0.20–0.28 in) long and the stamens 4–6 mm (0.16–0.24 in) long. Flowering mainly occurs from October to November and the fruit is a capsule 7–10 mm (0.28–0.39 in) wide with woody valves and that remains on the plant at maturity.[2][3]
