About
Boronia alata, also known as winged boronia, is a flowering shrub. It is an endemic species of Southwest Australia which has been introduced elsewhere as a cultivated plant.
How to grow it
Boronia alata is cultivated as an ornamental plant. It is able to be propagated from cuttings. As with most boronias, a heavily shaded situation is preferred for this species. The persistent flowers first appear in the austral spring, in a boronia form that is more open and 'star shaped' than concave or cupped; these are usually pink or infrequently white in colour. The native conditions can be simulated by providing well drained sand, with deep mulch or sandstone sheets that maintain available moisture and protect roots from higher temperature. The species was introduced to English gardens in 1824 as a small evergreen greenhouse specimen, flowering from May to July. The scent of the flowers is slightly fragrant. The vigour of its rootstock was recommended for grafting with Boronia pinnata for English enthusiasts.
Where it grows
The shrub occurs in Southwest Australia, with most records located at coastal areas. The disjunct records are from Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions. The habitat is dense vegetation on sand at dunes and limestone cliffs.
