Scilla Growing Guide
Scilla siberica
Crop Rotation Group
Miscellaneous ●
Soil
Average garden soil with excellent drainage.
Position
Full sun in late winter, partial shade in summer.
Frost tolerant
Excellent. Most scilla are hardy to -25F (-32C).
Feeding
Topdress with rich compost in spring, when new growth appears.
Companions
Scilla is one of the best little bulbs to naturalize in grass beneath deciduous trees. Scatter them in small groups along a woodland edge. Scillas combine well with crocuses and early-blooming daffodils.
Spacing
Single Plants: 3" (10cm) each way (minimum)
Rows: 3" (10cm) with 3" (10cm) row gap (minimum)
Sow and Plant
Set out dormant bulbs from late summer to early winter, planting them 4in (10cm) deep. Spacing can be as close as 2in (5cm) between scilla bulbs, which look best when planted in groups of seven or more.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.
Notes
Like crocuses, scilla are considered harbingers of spring. Expect scilla to spread when planted in a hospitable spot.
Harvesting
Seeds can be gathered and re-sown in early summer. Established clumps can be dug and moved in the fall, but are best left undisturbed.
Troubleshooting
Scilla needs a period of winter chilling, and will not persist long in warm climates.
