Crassulaceae: A vigorous perennial succulent typically up to 10cm high, with sprawling stems and stiff foliage resembling spruce branches, with softer tissue. Found on walls, shingle and warm grassy places on sandy soils. Clusters of yellow star shaped flowers. Blooming from July-August. The leaves are frequently blue-grey to grey but range to light greens and yellows. A plant has a prostrate, spreading habit. Native to northern, central, and southwestern Europe.
The plant can be eaten raw or cooked. A slightly astringent sour taste makes this plant a useful addition to a green tossed salad and it can also be added to soups or used as a vegetable. Used in salads, it has a fine relish.
These are very tiny seeds which should be mixed with finest sand or talcum for an even sowing. Do not cover with compost, only press them in gently. Irrigate from the bottom or with a hand-sprayer, so that the seeds will not be washed away. Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C [68°F]. Seeds must be covered thinly. Do not cover very small seeds, but tightly press into the earth. Keep in cooler conditions after germination occurs.
Requires a sunny position. The plant flowers best when grown in a sunny position, though it also succeeds in semi-shade. Established plants are very drought tolerant, they grow well in dry soils and can also be grown in a crevice on a wall. This species is hardy to about -15°C. A mat forming plant, it spreads rapidly, and it is not suitable for the rockery.
