Caryophyllaceae: a prostrate, downy, grey-green annual of dry, bare soils. The white, 5-pealled flowers are from 5-7mm across, blooming from May-September. The leaves are oval, in opposite pairs on slender stems. Widespread and common in the British Isles. Native to most of Europe, including Britain, temperate Asia and North America.
The entire plant is used as a pot-herb.
The plant has antitussive, depurative, diuretic and febrifuge properties. A decoction of the leaves is used in the treatment of dysentery. It is also used in the treatment of bladder complaints, calculus troubles and acute and chronic cystitis.
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. Grow in well-drained bare soil in full sun.
