Melaleuca alternifolia: is a
member of the Myrtaceae family in company with Callistemons (Bottlebrushes),
Eucalypts and Leptospermums (Tea Trees). There are about 220 Melaleuca species
with 215 native to Australia and the others scattered through New Guinea,
Indonesia and South-east Asia. As with many native plants, Western Australia
has the lion’s share of Melaleucas. Many of these western species are
outstanding plants with great horticultural potential.
Melaleuca alternifolia is an eastern species and occurs on the North
Coast and adjacent ranges of New South Wales. It develops into a tall shrub
with papery bark and white spring and summer flowers. The common name,
Snow-in-Summer refers to the flowers. Melaleuca alternifolia shares
this name with Melaleuca linariifolia another eastern species.
Melaleuca alternifolia has aromatic foliage and valuable oil is
extracted from the leaves. Tea Tree Oil has great germicidal properties and is
used in a range of products. Antiseptics, deodorants, shampoos (for dogs and
humans) and soaps are some of the products incorporating Tea Tree Oil. Large Melaleuca
alternifolia plantations have been established on the North Coast of New
South Wales. We are not sure why it is called Tea Tree Oil, as this is the
common name of Leptospermums.
Horticulturally speaking, Melaleuca alternifolia will cope with dry and
wet situations. It develops into a tall upright shrub and is covered in white
flowers in the warmer months. A wide range of native insects visits the
flowers. The papery bark is another feature.
Propagate from seed of cuttings.
