Hosta Blue Heart

Blue Heart Hosta

Hosta 'Blue Heart' — a medium-sized blue hosta valued for its broad heart-shaped blue-green leaves and smooth, balanced mounded habit. The foliage has good substance and holds a cool blue tone well in shaded conditions, creating a calm, refined presence in the garden. Pale lavender flowers rise above the foliage in midsummer, adding soft seasonal color while the foliage remains the main ornamental feature.

A dependable blue hosta for woodland gardens, shade borders, edging, and mixed hosta collections. Its broad cool-toned foliage pairs especially well with gold or white-variegated hostas, ferns, and other shade perennials.
