Saltbushes as Garden Shrubs


There are several saltbushes in and around Busselton that can perform as garden shrubs. Most saltbushes come from the Chenopodiaceae family and unsurprisingly, true to their name, are very salt tolerant. The Australian flora has many species that fit into this category. The main garden genera are Atriplex, Rhagodia, and Maireana, but there are other genera.
Note: some chenopodiaceae species are called samphires, and are not generally used in gardens as they grow in salty marshes, and sometimes right to the seawater edge. However, there is an interesting note on their cultivation in the Encyclopaedia of Australian Plants suitable for cultivation (details on the book page).
A near-complete listing of the salt-tolerant species of the Busselton district can be found here.

A few months ago, the Atriplex isatidea in this garden were towering sculptures, but this garden is expertly maintained with judicious pruning. Notice the fresh growth in the photos above.

Foliage Contrast

This award winning garden (Kwinana Beautiful Gardens Competition)  developed by horticulturalist Ross Boydell uses the Atriplex as a 'grey foil' to green shrubs, mostly Australian species, (extensive use of a Myoporum insulare) but also some exotics, like the Californian Lilac, Ceanothus papillosus var. roweanus 'Blue Pacific' which has a wonderfully deep green foliage. Other foliage-contrast species used in the garden are a variegated form of Westringia fruticosa (Eastern States' species), photos below, and a variegated Agonis flexuosa.

As a coastal species, Atriplex isatidea is pruned by the wind and salt spray, but in a garden setting, it requires regular pruning. Most Australian shrubs require regular pruning.
