Distribution Map
Family: Myrtaceae
Distribution: Heath and sandy areas in the south west of Western Australia.
Common Name: Sand bottlebrush
Derivation of Name: Beaufortia...after the Duchess of Beaufort, a botanical patron
squarrosa... From Latin squarrosus, rough or scaly, possibly referring to the leaves of this species.
Conservation Status: Not considered to be at risk in the wild.

General Description:

Beaufortia is a small genus of 22 species*, all of which occur naturally only in south Western Australia. The genus is closely related to the more familiar Melaleuca, both genera having stamens which are joined into clusters. The difference between the genera is in the arrangement of the anthers (the pollen bearing structures of the flowers). In Beaufortia these are attached to the stamens at their bases (basifixed) whereas in Melaleuca the anthers are attached along their sides (versatile).

B.squarrosa is a small to medium shrub about 1.5 to 2 metres high. The small leaves are oval-shaped, tapering to a point, and about 5 mm long. The bright red (occasionally yellow or orange) flowers occur towards the ends of the branches in globular-shaped clusters and are conspicuously displayed. Flowering occurs mainly in spring. Following flowering, seeds develop in woody capsules similar to those formed with Melaleuca species. The seeds are retained within the capsules indefinitely.

B.squarrosa is a very attractive garden plant for climates with low summer humidity. Cultivation in humid, east-coastal areas has been attempted but success has been mixed. Plants have been successfully flowered in Sydney but they cannot be regarded as reliable in that area - better results have been reported from areas west of the Great Dividing Range. It requires well drained conditions in full sun or dappled shade and it is tolerant of at least moderate frost.

Propagation is relatively easy from seed which germinates well without any pretreatment. Cuttings of hardened, current season's growth are also successful. Grafting onto reliable Melaleuca rootstocks may offer a solution to more widespread cultivation of this and other beaufortias but it is unknown if any experiments have been attempted.
