Wahlenbergia queenslandica is a small herbaceous plant in the family Campanulaceae native to Western Australia, to New South Wales, Queensland, the Northern Territory, and South Australia.[1]
The straggling to erect to ascending perennial herb typically grows to a height of 0.3to. It blooms between April and September producing blue-purple flowers in WA. However, in the Northern Territory it flowers from February through to December and fruits from February to November, while in NSW it flowers throughout the year.[1]
It is similar to W. communis: both have large corollas with long lobes, however W. communis differs in having a strictly alternate leaf arrangement, long hairs on the inner surface of the corolla tube near the base, and obconical (and frequently more elongated) fruit.[2]
The species is found on the edges of swamps and creek beds and damp flats in the Kimberley region of Western Australia where it grows in sandy-loam soils. In the Territory it is found on mulga-dominated plains, alluvial plains and intermittent watercourses.[2]
