Hosta 'Krossa Regal'

Hosta, Krossa Regal Plantain Lily, Plantain Lily

Hosta 'Krossa Regal' — a large, elegant blue hosta prized for its distinctive upright vase-shaped habit and long, pointed blue-gray leaves. The foliage arches outward from tall leaf stalks, creating strong vertical structure that sets it apart from broader mounding hostas. Pale lavender flowers appear on tall scapes in midsummer, rising well above the foliage and adding graceful seasonal interest.

Features & Landscape Uses:
One of the best hostas for adding height and architectural form in woodland gardens, shade borders, and specimen plantings. Its upright habit pairs well with broad-leaved hostas, ferns, and astilbes, and thick foliage offers some slug resistance.

Care:
Plant in rich soil with consistent moisture and mulch annually. Shade helps preserve the blue leaf coating. Remove spent flower stalks after bloom and cut back old foliage in early spring. Allow mature clumps space to develop fully for best form. 🌿
