Lechenaultia expansa is a prostrate or erect subshrub that typically grows to a height of up to and has wand-like branchlets. The leaves are glabrous, crowded, long, narrow and fleshy. The flowers are arranged in dense clusters in leaf axils, the sepals long and glabrous. The petals are long, pale purplish-blue, sparsely hairy and joined at the base to form a pale yellowish-white tube, the petal wings wide. Flowering occurs from October to January and the fruit is long.[1]
Lechenaultia expansa was first formally described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[2] [3] The specific epithet (expansa) means "spread out" or "unfolded".[4]
This lechenaultia grows in and near swampy heath and winter-wet areas in near-coastal areas of south-western Western Australia in the Avon Wheatbelt, Jarrah Forest, Mallee, Swan Coastal Plain and Warren biogeographic regions.[1]
