‘Sultry Night’ is a striking perennial prized for its dramatic, near-black, deeply ruffled foliage with a subtle purple overlay — a bold contrast in the garden even when not in bloom. The leaves emerge glossy in spring and maintain their rich dark tones all season, forming a dense, compact mound that works beautifully in front-of-border plantings, containers, or shaded edging. In mid-summer, airy flower spikes rise above the foliage carrying delicate, bell-shaped blooms that attract butterflies, hummingbirds and bees. Its refined structure and rich foliage make ‘Sultry Night’ a standout for texture, contrast, and low-maintenance, year-round interest.
