'Red Velvet' has large cherry red flowers. The tallest variety in the collection. Newly emerging foliage has a bronze cast. Well branched stems support a second flush of flowers that extends the length of bloom, a trait that will delight both gardeners and the bees who frequent this popular pollinator perennial. Members of this collection all exhibit good mildew resistance. The flowers' sweet nectar attracts scores of hummingbirds, butterflies, and bees to the garden.
