Much smaller than C. cordifolia, this is grown as much for its glaucous blue-green foliage as for its flowers which are white, appearing on short, stout stems. The foliage is particularly attractive when it first appears.

Best in very well drained soil and full sun. Usually found wild growling on coastal sand dunes or shingle. Very drought tolerant.

From seed or by root cuttings taken in winter.

Ideal for gravel plantings, especial in coastal areas.
The stems are edible and apparently very tasty when lightly cooked.

other notes:
From the coasts of North West Europe, including Britain, and the Black Sea.
