Hosta x ‘Krossa Regal’ is a striking non-native perennial prized for its large, frosty blue-gray foliage and tall scapes of lavender trumpet-shaped flowers that rise above the clump in mid to late summer. Known for its upright, vase-like habit, this cultivar can reach 3 feet tall with flower stalks up to 5 feet high. It performs best in part to full shade and rich, consistently moist soils. With its bold foliage and strong form, ‘Krossa Regal’ adds elegance and structure to shaded borders, woodland gardens, and foundation plantings.

Why choose ‘Krossa Regal’ Hosta:

• Bold texture: Large blue-gray leaves add contrast and depth to shade gardens

• Summer flowers: Lavender blooms attract pollinators and rise on tall stalks

• Architectural form: Upright habit provides vertical structure in low-light spaces

Cultivating tips:

• Sun exposure: Best in part to full shade

• Soil needs: Rich, moist, well-drained soils with organic matter

• Maintenance: Easy care; divide clumps every few years to maintain vigor

Designs for your garden:

• Shade borders: Perfect for pairing with ferns, astilbes, and woodland natives

• Foundation beds: Provides season-long structure with minimal care

• Understory planting: Great for filling space beneath trees and large shrubs

Ecological considerations:

• Non-native cultivar: Provides some pollinator support, but limited ecological benefit
