About

Mānuka (Māori pronunciation: [ˈmaːnʉka]; Leptospermum scoparium) is a species of flowering plant in the myrtle family Myrtaceae, native to New Zealand (including the Chatham Islands) and south-east Australia. Bees produce mānuka honey from its nectar.

The Latin specific epithet scoparium means 'like broom', referring to Northern Hemisphere genera such as Genista and Cytisus which it resembles in both general habit and in the landscape, sharing a preference for dry and exposed sites and poor soils, although it is only distantly related.

How to grow it

Numerous cultivars have been developed for garden use, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:

Uses

In traditional Māori culture, mānuka was used for a wide variety of uses, including as a building material, for items such as combs, paddles and digging sticks, to construct eel weirs, for weaponry, and to construct pallisade walls of pā. The plant also had uses in traditional rongoā medicine, with infusions being made from leaves, or by collecting mānuka gum.
