Although it blooms several weeks after spring snowflake (Leucojum vernum), summer snowflake blooms in mid-spring (late April), not in summer. It usually goes dormant by summer. Dark grassy green leaves to 12” long and 1” wide form an upright, vase-shaped clump of foliage. Typically 2-5 (less frequently to 8) white, nodding, bell-shaped flowers appear at the top of naked hollow flower scapes (to 12-15” tall) in spring. Each flower has three similar looking sepals and petals (tepals) that are spotted at the tip with green.
No serious insect or disease problems.
Borders, rock gardens. Under trees or shrubs. Best planted in groups of at least 15 bulbs. Can put on a spectacular flowering display when naturalized in large drifts
