Commelina erecta

No, not the invasive Asiatic annual Commelina communis, but the native perennial dayflower from prairies and other dry habitats through much of North America. Entrancing flowers with two large sky-blue mouse-ear upper petals and a small white lower petal open in summer on sprawling stems.  Excellent in wildflower plantings and cottage gardens, where it will seed around.

Sun to light shade; average to dry soil (drought tolerant); 12"x15"; summer; Zone 3

Propagated from seed; deep 3.5-inch pots
