Vervain

A perennial species of Verbena native to North America. In natural habitats, it grows in wet meadows, pastures, and along water bodies. It is a great attraction for bees and butterflies. Although not very long-lived, it can maintain itself in good conditions by self-seeding. It blooms gradually over a long period with many tiny flowers. The spent inflorescences are also effective, both in beds and in bouquets. White Spires is an elegant cultivar with pure white flowers.
