Growing notes

Light

Full sun to part shade — in borders, rock gardens, under shrubs or deciduous trees, and in pots.

Soil

Average, moderately fertile, well-drained soil; it grows in chalk, clay, loam or sand. pH about 6–7.

Care

Plant bulbs in autumn 8–10 cm deep and about 8 cm apart, in drifts of 25 or more. Keep the soil moist while it grows and flowers in spring, then water less as the leaves die back; the bulbs rest from late spring until new leaves appear in autumn, and the untidy winter leaves are normal. It spreads by offsets and seed and can become invasive, so in a small bed grow it in a pot. Lift and divide congested clumps in summer, while dormant, every four to five years. It is usually trouble-free; deer sometimes graze it, and rust, bacterial soft rot or viruses occasionally appear. The ASPCA lists grape hyacinth as non-toxic to dogs, cats and horses, but the bulbs are not for eating.
