Scilla 2015

Siberian squill, grown from a small bulb, is probably the most familiar of the scillas. The plants themselves don’t get much taller than about 6 inches, but they make up for their diminutive size by spreading out and blooming profusely. The tiny bulbs grow and multiple easily and the plants will also self-seed, making scilla a perfect choice for naturalizing.
