One could easily overlook this little plant – it is quite small, very low-growing and its flowers are tiny. Only about 8 cm high, it bears 2-3mm flowers which sometimes have 4 pale green-white petals – very often none at all. There are 4 purple-green sepals which are larger than the petals (not much help if they are absent), and they grow on purplish, fleshy, branching stems. They flower between May and September, if at all. The leaves are dark green, fleshy and the tip is blunt – unlike the leaves of Procumbent Pearlwort where there is a bristle-tip at the end of the leaves. This plant grows on bare, rocky ground, shingle, wasteground by the sea and in masonry by harbours. An native annual, occasionally found in coastal habitat, it belongs to the Caryophyllaceae or Pink family.
I found and photographed this plant at Slade, Co Wexford in August 2012 when on a BSBI Field Trip.
