Verbena bonariensis (Verbenaceae)
A cottage-garden classic that is simultaneously whimsical and sophisticated. In late spring, abundant tufts of lavender flowers appear to float in midair atop tall and slender, symmetrically-branching stems. This drought-tolerant, sun-loving plant is a wonderful addition to the middle of the border, creating an airy veil in front of more substantial perennials. Though they bloom profusely for months on their own, cutting back in midsummer will increase flowering in late-summer-to-fall. This Verbena is beloved by hummingbirds, and dried seed-heads are an absolute favorite of goldfinches, who bend and sway on the narrow stems. It tends to be a short-lived perennial, but readily self-sows for a continued presence in the garden.
