The Blue Vervain blossoms have mostly gone to seed. In the buffer around the pond, they've been blooming since mid-July. The flowers of Verbena hastata open one by one from the bottom of spikes held on the crown of the plant. This Monarch butterfly looked for nectar in the few remaining flowers at the top of the spike. Along with butterflies, bees and other insects visit Vervain. Now, the seeds will be food for birds like Cardinals, Sparrows, and Juncos.
