It is a compact shrub, its new growth densely covered with star-shaped hairs, and has mostly narrowly leaves and many deep blue to purple flowers arranged in groups of 4 to 10.

The flowers are deep blue to purple, the petals are absent, and the stamens have golden filaments and tiny staminodes.

[3][4] This species was first formally described in 1845 by Ernst Steudel, who gave it the name Keraudrenia integrifolia in Lehmann's Plantae Preissianae from specimens collected near the Swan River in 1839.

[5][6] The specific epithet (integrifolia) means "whole-leaved", referring to the leaves that lack serrations or lobes.

[8][9] Seringia integrifolia grows in heathy shrubland and open woodland between Carnamah and Quairading with a disjunct population near Hopetoun in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain and Yalgoo bioregions of south-western Western Australia.
