Species:L. scoparium

Leptospermum scoparium (Manuka or Tea tree or just Leptospermum) is a shrub or small tree native to New Zealand and southeast Australia. It is found throughout New Zealand but is particularly common on the drier east coasts of the North Island and the South Island, and in Australia in Tasmania, Victoria and New South Wales. Manuka (from Māori 'mānuka') is the name used in New Zealand, and 'tea tree' is a common name in Australia and to a lesser extent also in New Zealand. This name arose because Captain Cook used the leaves to make a 'tea' drink. The common name "Tea Tree" is also shared with the related Melaleuca tree of Australia suggesting that both were used to make tea by Captain Cook.

It is a prolific scrub-type tree and is often one of the first species to regenerate on cleared land. It is typically a shrub growing to 2-5 m tall, but can grow into a moderately sized tree, up to 15 m or so in height. It is evergreen, with dense branching and small leaves 7-20 mm long and 2-6 mm broad, with a short spine tip. The flowers are white, occasionally pink, 8-15 mm (rarely up to 25 mm) diameter, with five petals. This species is often confused with the closely related species Kānuka - the easiest way to tell the difference between the two species in the field is to feel their foliage - Manuka leaves are prickly while Kanuka leaves are soft. The wood is tough and hard, and was often used for tool handles. Manuka sawdust imparts a delicious flavour when used for smoking meats and fish. Manuka products have high antibacterial potency for a limited spectrum of bacteria and are widely available in New Zealand (usually as manuka honey which is now used in hospitals all over the world, especially for preventing infection and promoting healing in burns). Similar properties led the Māori to use parts of the plant as natural medicine.
