Hosta Carolina Blue

Carolina Blue Hosta

Hosta 'Carolina Blue' — a large blue hosta prized for its broad blue-gray leaves, strong substance, and bold mounded habit. The thick foliage carries a rich powdery blue coating that holds well through much of the season in shaded conditions, giving the plant strong visual presence and good slug resistance. Pale lavender flowers rise above the foliage in midsummer, adding soft seasonal color while the foliage remains the primary ornamental feature.

Features & Landscape Uses:
A bold blue specimen for woodland gardens, shade borders, foundation beds, and mixed hosta collections. Its cool foliage pairs especially well with gold hostas, white-variegated forms, and ferns.

Care:
Maintain consistent moisture and mulch annually to keep roots cool. Protect from strong afternoon sun to preserve the blue leaf coating. Remove spent flower stalks after bloom and clean old foliage in early spring. Mature clumps improve with age and need division only when crowded. 🌿
