Blue Vervain Flowering

7-29-14  blue vervain IMG_5431Blue Vervain (Verbena hastata) is a fairly tall (2 – 5 feet) flowering plant found in wet meadows. Its flower spikes branch upwards like the arms of a candelabra, and each has a ring of blue-purple flowers. The flowers at the bottom of the spike bloom first, and the ring of flowers advances upwards to the tips of the spike. Although Blue Vervain flowers have no scent, both long- and short-tongued bees are attracted to it primarily for its nectar, but also for its pollen. While Verbena Moth caterpillars feed on the foliage, most mammalian herbivores avoid eating this plant because of the bitter leaves. Various songbirds occasionally eat the seeds, including Cardinals, Swamp Sparrows, Field Sparrows, Song Sparrows, and Dark-eyed Juncos.

    Thanks for this timely post. I hadn’t seen this flower till the last couple of years, so I was worried it was another invasive — perhaps am on heightened alert what with it being loosestrife season. 😦
