Verbena hastata (Verbenaceae)
Airy candelabras of purple bloom appear from midsummer to fall — Edith Eddleman recommends this species as a "nifty see-through plant." More cold- and wet-tolerant, blue-violet in color, and reliably perennial than its cousin, "Verbena-on-a-stick" bonariensis. Plants have a sturdy and architectural form, with long and slender vertical seed heads that persist late into the season. Pinch back in midsummer for shorter growth and later fall flowering, or let them grow for tall summer blooming plants. Full sun and moist-to-average soil is ideal; truly wonderful interplanted with ornamental grasses. A traditional medicinal plant.
