Description and Ethnobotany

Growth Form Small tree or big shrub, up to 4m tall and wide, with densely-spreading crown and thin trailing branches, resembling a smaller version of Salix babylonica (Weeping Willow).
Trunk Bark peeling in thin strips, exposing brownish-pink smooth inner bark that ages to creamy-white upon further contact with air.
Foliage Leaves narrowly-linear, 5 - 7cm long by 3 - 4mm wide, held along reddish-brown twigs, emitting a fresh aromatic scent when crushed due to presence of an essential oil rich in monoterpenes (an antioxidant phytochemical also found in citrus fruits and vegetables).
Flowers Freely-produced, small and inconspicuous, 5mm across, 5 white petals.
Fruit Hemispheric in shape, 3 - 4mm across, woody and thin-walled, ripening from green to dark brown, before dehiscing to disperse seeds.
Habitat Endemic to Northern Territory of Australia, naturally distributed in sandstone gorges and along watercourses.
Similar Commonly sold under the misapplied name Leptospermum brachyandrum (New Territory / Pendulous form). The species form Leptospermum brachyandrum has non-pendulous crown. A less commonly-cultivated subspecies Leptospermum madidum ssp. madidum, endemic to Australia's Cape York, has slightly broader leaves and less pendulous crown.
Cultivation Slow-growing. Withstands wet sites and most types of soils. Drought-tolerant when established. Propagate by seeds. Stem and branch cuttings are typically difficult to root.
Etymology Genus epithet 'Leptospermum' derived from Greek terms 'leptos' (slender) and 'sperma' (seed), alluding to the small seeds produced by members of this genus. Species epithet 'madidum' means 'wet' or 'drenched' in Latin, a reference to the tree's natural riverine and moist habitats. Common name 'Tea-tree' derived from practice of Australia's pioneer settlers in boiling the leaves of several species to make a tea-substitute rich in ascorbic acid and antioxidants.
