In the garden

A bulbous perennial in the Amaryllidaceae, Leucojum aestivum is native from Europe to north Iran and produces white flowers in March to April. Mature clumps reach roughly 0.5 m and are often chosen for sites that remain damp through the growing season. Give the plants a sunny aspect and soils that can range from sandy or loamy to clay; they tolerate wet ground so long as drainage prevents permanent waterlogging. Soil described as moist but well-drained to wet suits them. In UK hardiness terms the species is H7 (fully hardy), and it also corresponds to USDA zones 4–9, so it withstands cold winters when planted outdoors. Because of its preference for moisture and tolerance of heavy soils, Leucojum aestivum fits damp borders, pond edges and moisture-retentive parts of larger herbaceous beds where other bulbs may struggle. Treat the bulbs as ornamental only: they should never be eaten, and protective gloves and equipment are advised when planting, dividing or lifting them.
