Grape Hyacinth

grape hyacinthspring bloomnaturalisingbulblow plant

Grape hyacinths are charming, small bulbs that produce dense clusters of cobalt-blue, bell-shaped flowers in March and April. They release a light, sweet fragrance and naturalise effortlessly, returning in ever-larger groups each year. Ideal for naturalising in lawns, under trees, or as edging along paths.

Care guide

Plant bulbs in autumn at about 8 cm depth in well-drained soil. Virtually any soil type is suitable. Choose a sunny to lightly shaded spot. After planting, almost no care is needed — the bulbs are fully hardy and self-sufficient.

Pruning tips

Allow the grass-like foliage to die back completely after flowering before removing it. Foliage sometimes appears in autumn — this is normal and should not be cut. Naturalized colonies need no thinning unless they crowd out other plants.

Common Hyacinth

The hyacinth is a beloved spring-flowering bulb with dense, cone-shaped flower clusters that release an intoxicatingly sweet fragrance. In March and April, blooms appear in blue, pink, or white above the stiff, glossy foliage. Hyacinths are perfect for borders, pots, and indoor forcing. The bulbs return each year, though the trusses become slightly looser.
