Tall, upright stems support striking clusters of vivid cobalt-blue, star-shaped flowers that stand out boldly against slender, green, strap-like foliage. Reaching up to 3 feet in height and spreading about 2 feet wide, these perennials grow more stunning with time. Ideal for garden beds, borders, or patio containers, they bring a dramatic pop of color throughout the warm season. Flowering begins just after the final spring frost and continues steadily until autumn’s first chill.
