Summer Snowflake Leucojum aestivum 'Gravetye Giant'
ABOUT
The plant known commonly as 'Summer Snowflake' is a charming perennial that produces delicate bell-shaped flowers. Each blossom is a dazzling white with small green spots at the tip of each petal, bringing a fresh and vibrant look to any garden setting. The flowers hang gracefully from the stem, nodding in the breeze and creating a whimsical display. The foliage of the Summer Snowflake is a bright green, forming linear and strap-like leaves that provide a lush backdrop for the pristine flowers. These blooms are typically arranged in an umbrella-like cluster atop a slender, erect flower stalk that rises elegantly above the leaves. This plant provides a burst of late winter to early spring beauty, with its blooms serving as a herald of the warmer months to come. The Summer Snowflake has a clumping habit, making it a great choice for naturalizing in a garden where it can create a carpet of white flowers when planted en masse.

WaterSummer Snowflake prefers consistent moisture, especially during its active growth in spring and early summer. It's best to water the plant once a week with about one to two gallons of water, ensuring the soil is kept moist but not waterlogged. During the dormant period in late summer to fall, reduce watering frequency to prevent rot. Always check the top inch of soil for dryness before watering, as overly wet conditions can lead to bulb decay. The exact amount of water may need to be adjusted depending on climate conditions such as temperature and rainfall.
LightSummer Snowflake thrives in dappled sunlight or partial shade areas. It's ideally positioned under the canopy of deciduous trees where it receives filtered sunlight. Direct sunlight can be tolerated in cooler climates, but in hotter regions, protection from the strong afternoon sun is beneficial to prevent leaf scorch. Morning light with afternoon shade is the optimal lighting situation for this plant, encouraging healthy growth without the harsh effects of intense sun.
TemperatureSummer Snowflake can tolerate a wide range of temperatures but performs best when the weather is cool to moderate. It can survive winter temperatures as low as 10°F but prefers the growing season temperatures to be between 50°F and 75°F. Extreme heat above 90°F can stress the plant and affect flowering, so in hotter zones, it is beneficial to provide shade to help maintain cooler soil temperatures.
PruningSummer Snowflake generally requires minimal pruning. Deadheading the spent flowers after blooming can be beneficial to prevent self-seeding, especially if you want to control the spread of the plant. Removing yellowed or dead foliage once it has naturally died back in late summer helps to keep the plant looking tidy and may reduce the likelihood of disease. Typically, this bulbous plant will only need pruning once a year after the foliage has yellowed and died back.
CleaningAs needed
SoilSummer Snowflake (Leucojum aestivum 'Gravetye Giant') thrives in well-draining soil enriched with organic matter, like compost or well-rotted manure. A balanced potting mix with peat, loam, and sand is ideal, ensuring good moisture retention yet allowing excess water to drain. The optimal pH range for Summer Snowflake is neutral to slightly acidic (6.0 to 7.0).
RepottingSummer Snowflake (Leucojum aestivum 'Gravetye Giant') bulbs should be lifted and divided every 3-5 years to prevent overcrowding and maintain vigor. It’s best to repot them after the foliage has died back, usually in late summer or early fall.
Humidity & MistingSummer Snowflake (Leucojum aestivum 'Gravetye Giant') prefers moderate humidity levels, typical of outdoor garden environments. Excessive humidity can lead to fungal issues, so ensure good air circulation if grown in more humid conditions.
Suitable locationsIndoor
Place Summer Snowflake in well-lit spot, away from dry heat sources.
Outdoor
Plant Summer Snowflake in partial shade, moist soil, and protect from strong winds.

Life cycleThe life cycle of the Summer Snowflake 'Gravetye Giant' starts with seed germination, occurring in moist, well-drained soil, typically in a cool, temperate environment. After germination, the plant develops a bulb, which will serve as an energy reservoir and anchor for the roots. The foliage emerges as strap-shaped green leaves, followed by the plant's characteristic white, bell-shaped flowers with green spots at the tip of each petal, appearing in spring. Post flowering, seed pods may form, which upon maturing, release seeds to propagate the next generation. Throughout the summer, the plant goes dormant, with the leaves dying back, and the bulb lying inactive underground. In subsequent springs, the cycle repeats, with the bulb sending up new growth to start the process anew.
PropogationPropogation time
Late summer
The most popular method for propagating Summer Snowflake, officially known as Leucojum aestivum 'Gravetye Giant', is through bulb division. This is best done when the plant is dormant, typically from late summer to early fall. To propagate by division, carefully lift the clump of bulbs from the ground using a spade, ensuring minimal damage. Gently separate the bulbs, making sure that each offset has a portion of the basal plate to ensure successful growth. Replant the bulbs immediately at a depth of about 3 to 4 inches (roughly 7.5 to 10 centimeters) and space them approximately 6 inches apart (about 15 centimeters). Water the newly planted bulbs well to help establish them. By the next growing season, these bulbs should mature and flower, continuing the lifecycle of the Summer Snowflake.
