Melaleuca irbyana

Swamp Tea Tree

Family: Myrtaceae

Melaleuca irbyana, Swamp Tea Tree, develops into a large shrub or small tree in the wild. In our cold climate garden plants only reach a height of about one metre. Plants, in another local garden, have grown into a similar size.

Melaleuca irbyana grows in open eucalypt forests on poorly drained sites. Our plants are probably restricted in size because they are growing in well drained, rather dry sites.

The bark is spongy and papery. Branches are pendulous with small leaves with taper to a point and are pressed against the branches. Flowers are white, scented and held in terminal spikes up to 2.5 centimetres long. Each spike is composed of 3-12 individual flowers. Flowers appear from September to January. Small, woody fruits are flattened spheres. Seeds are released when they mature.

Melaleuca irbyana is classified as a threatened species in both NSW and Queensland.


In the garden

In our garden plants are grown as foreground specimens in garden beds. Growth habit, foliage and flowers are all attractive features. Tip pruning is appreciated.


Propagate from seed and cuttings.
