'Krossa Regal'
Hosta
Hosta ‘Krossa Regal’ is known for its striking upright, vase‑shaped form — a sculptural silhouette that instantly sets it apart from traditional mounding hostas. The tall, elegant leaves are a cool, silvery blue‑green with a subtle glaucous finish that holds beautifully in shade, giving the plant a refined, architectural presence. In midsummer, tall scapes rise well above the foliage carrying soft lavender flowers that add height and movement without disrupting the clean structure below. Thriving in part to full shade with moist, well‑drained soil, it matures into a commanding, long‑lived hosta ideal for creating vertical interest in woodland borders, shaded foundations, and layered plantings.
