Leucojum (Giant or Summer Snowflake) Planting Guide
Spring Snowflakes in the South, West or Anywhere!
Here's a bulb we can't recommend highly enough for dependable spring blooms virtually across the country. In the heat and humidity of the South, they persist, bloom lushly and develop into big clumps. In the cold of the North, giant snowflakes shrug off the chill and pop up spring after spring. In the drier West, these stalwarts grow full and produce multiple arching flower stalks even in sandy soils. New to gardening or just moved to a new home and are unsure what to plant? Go with
giant snowflakes for sure fire success.
- Find a location where the soil drains well. If there are still water puddles 5-6 hours after a hard rain, scout out another site. Or amend the soil with the addition of organic material to raise the level 2-3" to improve the drainage. Peat moss, compost, ground bark or decomposed manure all work well and are widely available. While
leucomjum aren't fussy about soil, they will not survive in soggy soil or standing water.
- These bulbs thrive in a variety of light conditions, from full sun to partial shade to dappled shade, making them easy to site and easy to please. The most pleasing results are achieved when bulbs are grouped together, five or more to a patch.
- Dig holes and plant the bulbs 4" deep and 4" apart. Bulbs have pointed tops and flat bottoms; plant with the points oriented up. If left undisturbed, over time small side bulbs will develop and create big blooming clumps.
- After planting, water well, gently soaking the soil and settling it around the
bulbs. Roots will form in the autumn. Leaves and flowers will develop in the spring.
- When in bloom, feel free to cut flowers for lightly scented spring bouquets. This will not hurt the plants.
- After blooming has finished for the season leave the foliage in place; don't cut it off. The leaves will gather sunlight, create food through photosynthesis and strengthen the bulb for the future. Water as needed
during active growth periods; about 1" of moisture per week is a good estimate.
- By early to mid summer the leaves will yellow and die back as the plant slips into dormancy. Foliage many be removed at this point. Your giant snowflakes will rest for a few months before beginning the next growing cycle.
Pots, Barrels, Tubs & Urns
Giant snowflakes do best when the bulbs are left undisturbed for long periods of time. For this reason they are not recommended for containers.
