In this species, a sterile, naked area in the middle of the cat-tail separates the lower female section from the upper male part of the bloom. In marshy wetlands, plants spread rapidly into colonies and provide water purification and shelter for wildlife. Cat-tails are handsome grown in containers, either above ground or sunk in the garden to prevent spreading. Sunny, wet locations are perfect for planting. Great for floral arrangements and for winter interest.
Flowers tend to be in flattened panicles or clusters and bloom continuously if deadheaded.
Generally, they are very heat and drought tolerant. This 4-5' Verbena is a wonderful addition to the middle of the border, creating a veil to heavier foliage and flowers. Many who visited had to have a plant. If you cut it back by half when the flowers fade, you'll get a second flush of bloom in late summer. Provides an ethereal effect in the garden.
