Tall verbena or purpletop vervain, is a striking, upright tender perennial prized for its tall, wiry stems and clusters of small, lavender-purple flowers. Blooming from mid-summer to fall, it adds height and a light, airy texture to borders and pollinator gardens. Loved by butterflies and bees, it thrives in full sun and well-drained soil, self-seeding readily to return each year with minimal care. Its open structure makes it perfect for weaving through other plants without overwhelming them. 100cm.
