Photo Compliments of Ian Sutton

Leucojum aestivum, summer snowflake blooms in mid to late April, and typically goes dormant by summer. This plant produces dark, grassy green leaves to that reach a length of 12 inches and are about 1 inch in width. Summer snowflake forms an upright, vase-shaped clump of foliage.

There are typically 2 to 5 (sometimes up to 8) white, nodding, bell-shaped flowers that appear at the top of a naked hollow flower scape (12 to 15 inches in height) in spring. Each flower has three similar looking sepals and petals (tepals) that are spotted at the tip with green.

How to Make Your Leucojum Aestivum, Summer Snowflake Thrive

Summer snowflake is easily grown in organically rich, medium moisture, well-drained soils in full sun to part shade; it will adapt to clay soils.

When you are planting bulbs in the fall they should be 3 to 4 inches deep and 4 to 6 inches. Bulbs are best left undisturbed once set in the ground; this plant will naturalize by bulb offsets.
