Conospermum huegelii

Conospermum huegelii, commonly known as the slender smokebush, is a species of flowering plant endemic to the south-west of Western Australia. It is a low, clumped shrub with thread-like to narrowly cylindrical leaves, and spikes of pale blue to cream-coloured, tube-shaped flowers and hairy nuts.

Description

Conospermum huegelii is a low, clumped shrub that typically grows to a height of up to, up to high when in flower, and does not form a lignotuber. Its leaves are upright, thread-like to narrowly cylindrical, long, wide and curved or spirally coiled. The flowers are spikes on the ends of branchlets on a peduncle long with egg-shaped, glabrous blue bracteoles. The flowers are pale blue to cream-coloured and form a tube long. The upper lip of the perianth is egg-shaped, long, wide, and curved backwards, the lower lip joined for with narrowly oblong lobes long and wide. Flowering occurs from
July to October, and the fruit is a nut long and wide and covered with woolly golden brown to orange hairs.

Taxonomy

Conospermum huegelii was first formally described in 1838 by the botanist Stephan Endlicher from an unpublished description of Robert Brown. Endlicher's description was published in Stirpium Australasicarum Herbarii Hugeliani Decades Tres from specimens collected near the Swan River Colony by Charles von Hügel. The specific epithet honours the botanist Karl von Hugel.

Distribution and habitat

Slender smokebush is found in swampy areas and among granite outcrops in the Swan Coastal Plain and in the Darling Range of Western Australia where it grows in sandy-gravelly soils in the Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.

Use in horticulture

This attractive ornamental plant is suitable for gardens or containers. The flowers are used for decoration and are long lasting. It is reasonably difficult to establish, propagation is by cuttings and can be sown by seed.
