This pest-free perennial blooms best during warm months. It is strange how these small blue flowers attract butterflies more than large-blooming, showy neighbors. Blue porter weed gradually reseeds nearby for a fresh batch of new plants. Mix with other species of Stachytarpheta for a variety of leaf shapes and colors ranging from purple to coral.
