Leucojum aestivum ‘Gravetye Giant’

summer snowflake

Outstanding Qualities

Leucojum aestivum 'Gravetye Giant' is a bulbous perennial with erect, strap-shaped, glossy dark-green leaves to 16 inches. In spring, leafless stems that are up to 36 inches in height bear up to 8 bell-shaped, slightly chocolate scented, white flowers. Gravetye Giant is a standout of this genus because of its vigor. It is more robust, taller and a heavier bloomer. Its common name, summer Snowflake is a misnomer because it blooms in spring and by summer it has gone dormant and is just a memory. This plant is a great naturalizer and looks good with other spring ephemerals such as tulips and daffodils. It is also a good choice for planting between later-season perennials.

Culture Notes

Summer snowflake grows best in full sun to light or open shade. Like daffodils, grow them under shrubs and trees that are leafless in late winter and early spring. This bulb likes a moist to well-drained soil, but will tolerate sand or clay. It prefers not to completely dry out in the summer while dormant and will survive in locations where the water puddles in the winter. Plant it in a location with occasional water during dry weather. It is best to plant the bulbs in fall. The foliage can be cut back in early summer once it has started to yellow.
