Verbena hastata
Swamp Verbena features purplish-blue flowers, which bloom on tall spikes, a few at a time from bottom to top, June-September. The flowers are a nectar source for bees and butterflies. Swamp Verbena is a host plant for butterfly and moth larvae (caterpillars), including Common Buckeye (Junonia coenia). This plant prefers moist soil conditions. Use it in rain gardens, along water features, or in other moist areas of the yard. It can also be planted in borders and meadows.
