Blue squill is excellent for naturalizing beneath trees that lose their leaves, where it will form drifts of singing blue bells in early spring. Needs a few years to really hit its stride. Capable of self-sowing. Try it with early daffodils such as Tete-a-Tete.

Full sun or partial shade. Well-drained soil. Blue squill can self-sow with abandon: If left undisturbed, a handful of bulbs may eventually become a thick, brilliant blue carpet in spring. Can be naturalized in a lawn if you’re willing to hold off on mowing until the seed capsules open and the foliage begins to yellow.
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.
