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.

Pests and Diseases
Summer snowflake has no serious insect or disease problems; this is a wonderfully robust plant.
Propagate by seeds in containers in a cold frame in autumn, or you can remove offsets once the leaves have died down.
This plant can very effectively be used in borders, and rock gardens; it will easily thrive under trees, or shrubs.
My suggestion is to in groups of at least 15 bulbs, it will put on a spectacular flowering display when naturalized in large drifts.
