About

Kunzea ambigua, commonly known as white kunzea or tick bush, is a species of flowering plant in the family Myrtaceae and endemic to eastern Australia. It is an erect shrub with linear to narrowly lance-shaped leaves and white, more or less sessile flowers and dehiscent fruit.

How to grow it

It was one of the first species of Australian plant introduced into cultivation in England. It is a hardy and adaptable plant that is used in windbreaks and sand dune stabilization plantings, as well as gardens, particularly in Australian gardens using native plants according to principles of natural landscaping. The species attracts Australian native insects, and can provide shelter for small birds and the long-nosed bandicoot (Perameles nasuta).

Where it grows

Kunzea ambigua is found from northeastern New South Wales, having been recorded in the Grand High Tops of the Warrumbungle National Park, through Victoria and into Tasmania. It grows on sandy soils in coastal or near-coastal regions. It is a very common dry forest shrub of the Sydney region, and regenerates in disturbed or cleared areas. It is associated with scrub she-oak (Allocasuarina distyla), Melaleuca nodosa, cheese tree (Glochidion ferdinandi) in heath or scrub, and with red bloodwood (Corymbia gummifera), peppermint gum (Eucalyptus piperita), forest red gum (Eucalyptus tereticornis), woolybutt (E. longifolia), thin-leaved stringybark (E. eugenioides), and white feather honeymyrtle (Melaleuca decora) in forested areas. In Wilsons Promontory in Victoria, Kunzea ambigua is the dominant species within scattered areas of treeless heath that occur on granite hills and mountains.
