Grown in dry bare places, or on rocks, walls or mountains.

A very low plant, less than three inches high, with a basal rosette of leaves and no stem leaves. Each plant can have a few narrow stems, with small groups of flowers atop.

The leaves are all basal, with no stem leaves. In this specimen the leaves are sparsely toothed near the end, another example of the variability of this plant.

The oval cross-section of the seed pod is in evidence here, as is the shuttlecock-like nature of the flowers before fully opening.

Un-opened flower buds are small and spherical.

Green flattened oval pods.

The basal rosette of leaves may or may not be toothed; the plant is very variable.

The leaves are sparsely covered in hairs arising from small pimples on the surface.


Not to be confused with : Grass Of Parnassus, Sea Arrow-grass, Marsh Arrow-grass, Sparrowgrass, Danish Scurvygrass, Common Scurvygrass, English Scurvygrass, Pyrenean Scurvygrass, Eelgrass, Yellow-Eyed Grass, Blue-eyed Grass, Grass Poly, Grass-leaved Orache, Grass-wrack Pondweed or Grass [plants with similar names].

Not to be mistaken for : Hairy Whitlowgrass (Erophila majuscula) or Glabrous Whitlowgrass (Erophila glabrescens) which have petals deeply cleft to only half-way rather than more than half-way in the case of Common Whitlowgrass. Also, Hairy Whitlowgrass is covered in densely grey downy hairs whereas Common Whitlowgrass is sparsely hairy, and Glabrous Whitlowgrass is sparsely downy rather than sparsely hairy.

Differentiated from most other Whitlowgrasses by : the deep cleft (over half-way) in the four petals.

Slight resemblance to : Mouse-ears and Stitchworts which mostly also have deeply cleft petals, but they have five rather than four petals. Of the Mouse-ears, only Grey Mouse-ear has four rather than five petals, but it is silvery grey.

Common Whitlowgrass flowers early in the season and grows in dry places such as walls, rocks, mountains and bare dry places.
