Scilla Siberica 'Alba'

Siberian Squill

Scilla siberica 'Alba', also known as White Siberian Squill, is a bulbous perennial that produces pure white, bell-shaped flowers in early to mid-spring. Each bulb yields 2–5 nodding blooms per stem, creating a delicate, snow-like effect in the garden.

This variety thrives in full sun to partial shade and prefers average, well-drained soil. It is one of the most winter-hardy scillas, capable of surviving in Zone 2. Growing 3–6 inches tall, it is an excellent choice for naturalizing, forming large drifts that return year after year.

Growing and Maintenance Tips for Scilla Siberica 'Alba'

Planting: Plant bulbs in fall, 3 to 5 inches deep with the pointed end up. Ideal for naturalizing in lawns, woodland edges, or under deciduous trees.
Spacing: Space 2 to 4 inches apart. These bulbs spread readily by seed and offsets.
Light: Prefers full sun to partial shade. Spring sun before trees leaf out is perfect.
Soil: Well-drained, humus-rich soil with a neutral to slightly acidic pH. Avoid soggy spots—bulbs may rot.
Watering: Water during active growth and bloom. Once foliage yellows, reduce watering—bulbs prefer dry summer dormancy.
Temperature & Humidity: Extremely cold-hardy (USDA zones 2–8). No need to lift bulbs in winter.
Fertilization: Apply compost or a low-nitrogen bulb fertilizer in early spring as foliage emerges.
Pruning: Allow foliage to die back naturally. Deadhead to reduce self-seeding if desired.
Propagation: Multiplies by offsets and self-seeding. Divide clumps every few years after dormancy.
Pest & Disease: Generally pest-free. Deer- and rodent-resistant. Good drainage prevents bulb rot.
