Very rare, now growing only on and around the Gower Peninsula. Surrounded by Sea Spurge.

Plant woolly hairy all over. Leaves shoe-horn shaped with and without the odd triangular teeth or longer rounded side-lobes. Flowers lilac blending to white, with four long narrow wedge-shaped petals.

Flowers have four cream-coloured anthers. Leaves a darker shade of greyish white than the flowering stems. Bare yellow leaves show at the tip of the leaves as if the white fur had worn away there.

Petals normally in a cross; on this specimen one of the petals is folded back over the middle. Petals slightly furry too.

Tips of leaves without fur. Smaller yellowish dots adorn the white felty fur; these will turn into the black dots mentioned by Blamey, Fitter and Fitter. These are hydathodes, a bit like leaky valves, which secrete excess water from the plant and operate alongside the stomata (which can open or close up in response to the environmenal moisture). They are also obvious on other plants from the Brassicaceae (Cabbage family) such as on the edges of the leaves of Dame's-Violet (Hesperis matrionalis) and typically visible on the leaves of many Campanula (Bellflowers).


Easily mistaken for : Lamb's-Ear - the leaves are similarly very felty hairy, but the flowers are vastly different.

Some similarities to : the less rare Hoary Stock, but that is less woolly with slightly larger purple, pink or white flowers and is fragrant and not as stout.

Uniquely identifiable characteristics

Distinguishing Feature :

Grows near the coast on sand dunes and rocky cliffs.

The pods are curved and result in a tangled un-tidy mess.
