What it's good for, and what it isn't

A tough perennial of dry loess grasslands whose garden cultivars carry dense, upright spikes of violet, blue, pink or white in early summer, always busy with bees. It wants sun and rather poor, well-drained soil and shrugs off drought; in rich, moist ground it grows lanky and flops. Cut it back to the basal leaves after the first flush and it flowers again in late summer. Cultivars differ in height and colour: 'Ostfriesland' and 'Blauhügel' are 40 to 50 cm tall in violet and blue, 'Mainacht' is an early, dark indigo, 'Schneehügel' is white, 'Rose Queen' pink, and the Sensation and Marcus series stay at just 25 to 30 cm for edging and pots.

Watch out for
In rich or irrigated soil, or in part shade, the stems fall open by midsummer; cutting back puts this right. In humid, crowded spots powdery mildew, leaf spot and rust can appear, occasionally aphids and whitefly too, though rarely seriously. In soil that stays waterlogged in winter the crown can rot.
