Hosta 'Hadspen Blue'

Hadspen Blue Plantain Lily, Hosta, Plantain Lily

Hosta 'Hadspen Blue' — a medium-sized blue hosta prized for its thick, heart-shaped powdery blue leaves that hold their color well through much of the season. The foliage forms a dense, rounded mound with a slightly cupped shape and smooth texture, giving it a clean, refined appearance in shade gardens. Pale lavender flowers rise above the foliage in midsummer, adding soft contrast to the cool-toned leaves.

Features & Landscape Uses:
A dependable blue hosta excellent for woodland gardens, shade borders, edging, and mixed hosta collections. Its cool foliage pairs beautifully with gold or variegated hostas, ferns, and astilbes. Thick leaves offer some resistance to slug damage.
