Average garden soil with excellent drainage.
Full sun in late winter, partial shade in summer.
Excellent. Most scilla are hardy to -25F (-32C).
Topdress with rich compost in spring, when new growth appears.
Crocus. 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.
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.
Like crocuses, scilla are considered harbingers of spring. Expect scilla to spread when planted in a hospitable spot.
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.
Scilla needs a period of winter chilling, and will not persist long in warm climates.
