Botanical name:  Leptospermum scoparium
Maori name:  Manuka
Common name:  Tea Tree
Height:  4 metres

A very important colonising plant. A small multi-trunked bushy tree with very flakey bark which is a haven for insects.

Small white flowers can be present from spring to early winter.  It is a rapid shade producer. 

There are about 85 species in the genus Leptospermum, mostly in Australia. There are a few in Malesia and one shared between Australia and New Zealand. (manuka, L. scoparium).

Maori used the leaves and bark of manuka for medicinal purposes.  The hard durable branches were fashioned into spears and lances. European settlers used wood for fence palings and tool handles and made brooms from twigs. Manuka leaves were used to brew a tea-like drink.

In modern times attention has turned to manuka honey. Some forms of this honey can contain additional antibacterial components which are superior to the acknowledged presence of hydrogen peroxide which occurs in all honey. This extra activity has been called the Unique Manuka Factor (UMF) and honey containing it has become known as active Manuka honey. Methylglyoxal (MGO) has recently been identified as the unique substance in active Manuka honey.
