Question:

What is the identity of the small, blue-flowering plant that blooms in April?

Answer:

The small, blue-flowering plant is probably Siberian squill (Scilla sibirica).  Siberian squill is an early spring flowering bulb.  Plants typically bloom in early to mid-April in Iowa.  Bright blue flowers are produced on 4- to 6-inch-tall plants.  Siberian squill is easy to grow and prefers partial shade.  It’s most effective when planted in masses under trees and shrubs and along woodland edges.  The flower spikes on ‘Spring Beauty’ (the most widely planted cultivar) are slightly larger than the species. Siberian squill multiplies rapidly.  The foliage of Scilla sibirica dies back to the ground by early June.
