Andersonia lehmanniana is a species of flowering plant in the family Ericaceae and is endemic to the south-west of Western Australia. It is a shrub with pointed lance-shaped leaves and white, cream-coloured or pink and blue or purple flowers.
Andersonia lehmanniana is a shrub that typically grows to a height of . Its leaves are lance-shaped with a pointed tip, long with the ends curved backwards. The flowers are arranged in heads of three to twelve or more, and have oblong sepals long, the petals white, cream-coloured or pink and blue or purple, forming a tube with lobes shorter than the petal tube and bearded inside.
Andersonia lehmanniana was first formally described in 1845 by Otto Wilhelm Sonder in Lehmann's Plantae Preissianae from specimens collected near Guildford in 1839. The specific epithet (lehmanniana) honours Johann Georg Christian Lehmann.
In 1962, Leslie Watson described subspecies pubescens (previously known as Andersonia pubescens <small>Sond.</small>), and that name, and the name of the autonym, are accepted by the Australian Plant Census.
This species of Andersonia grows in sandy soils on sandplains or hills between Geraldton and Hopetoun in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee and Swan Coastal Plain bioregions of south-western Western Australiai. Subspecies lehmanniana occurs in near-coastal areas and subsp. pubescens in more inland areas of the same regions.
Both subspecies of Andersonia lehmanniana are listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
