It is found in the northern temperate regions of the world, often growing in crevices or free-draining rocky soil. As a long-day plant it grows vegetatively for most of the year and flowers in summer. 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.
