Verbena hastata
Common name: Blue Vervain
Blue Vervain is a common plant in Illinois, enjoying wet muck and even some standing water from time to time. Blooms occur in late summer and last one to one and a half months. Flower spikes occur in terminal panicles and bloom from bottom to top. Flowers attract a whole range of bees, butterflies and other pollinators. Plants can spread by both rhizomes and seed, especially under ideal conditions.
