Experience the captivating charm of Iris foetidissima, commonly known as Stinking Iris or Gladwin Iris, a hardy perennial with distinctive appeal. Native to northern Africa and southern Europe, this unique plant is a versatile addition to any garden, thriving in Zones 6 to 9 and reaching up to 2 feet tall and 1.5 feet wide. Stinking Iris is celebrated not for its pale lilac blooms in May, but for the dramatic display of its coral-hued, bead-like seed clusters that emerge in autumn. These vibrant seeds are revealed as the seed capsules split open, remaining a stunning presence in the garden throughout the winter.

The rosette of evergreen, dark green, sword-shaped leaves, often described as "unpleasantly aromatic" when bruised, adds a structural element to the landscape. Stinking Iris is deer resistant, tolerates a range of light conditions from full sun to shade, and grows best in moist, humusy, well-drained soils, though it is surprisingly drought-tolerant once established. This low-maintenance plant is perfect for underplanting shrubs, borders, and cottage gardens. Awarded the Royal Horticultural Society's Award of Garden Merit, it's an exceptional plant for those seeking year-round interest with a touch of whimsy. Note: Toxic if ingested; handle with care.
