White Stonecrop (Sedum album)
White stonecrop is a tufted perennial herb that forms mat-like stands. Much of the year the stems are short, semi prostrate and densely clad in leaves. At the flowering time in July and August, the stems lengthen and are erect, occasionally branched and often pinkish-brown. The leaves are alternate, fleshy and nearly cylindrical with a blunt, rounded tip. They are also sometimes tinged with pink, especially in drought-stressed plants. The starry flowers form a dense cyme. The calyx has five fleshy sepals fused at the base, the corolla consists of five regular white petals, there are ten stamens, a separate gynoecium and five pistils. The fruit is five united, many-seeded follicles.
White stonecrop is a low-growing plant that cannot compete with more vigorous fast-growing species. It is specially adapted for growing on thin dry soils and can be found on walls, dry banks, seashore rocks and in rocky meadows.
