Calyx shorter than the bract, deeply 2-cleft, slightly 2-keeled, 1.5–2.5 mm long. Corolla purple or pink to white; limb at first white, afterwards lilac with a darker dot, 2–3 mm across, the lower lip twice as long as the upper one and about half as long as the tube.

This species is considered to be spreading rapidly and could be a menace in cultivated areas.
O'Leary et al. (2012) suggested that this taxon be treated as P. nodiflora var. minima. However, this opinion is not accepted. Therefore, Phyla canescens is here retained as a distinct species.
