Blue Hawaii Hosta

The 'Blue Hawaii' hosta ( Hosta 'Blue Hawaii') is a large, slow-growing perennial prized for its upright, vase-shaped form and thick, corrugated, powder-blue leaves. 

Key Characteristics

• Foliage: The large, heart-shaped leaves are a rich, powdery blue, with a heavy waxy coating that helps them hold their color well through the season when planted in the shade.
• Size: At maturity, the plant typically reaches a height of about 30 inches (76 cm) with a spread of around 4 feet (1.2 m).
• Flowers: Dainty spikes of fragrant, very pale lavender or white tubular flowers rise above the foliage in early to mid-summer.
• Growth Habit: It has a dense, upright, vase-shaped growth habit, providing an excellent architectural element in a garden.
  Hardiness Zone: It is hardy in USDA zones 3 to 9.

Growing Conditions

• Light: The 'Blue Hawaii' hosta does best in partial to full shade. To maintain its intense blue color, it needs protection from hot, afternoon sun, which can turn the leaves green.
• Soil: It prefers average to moist, fertile, well-drained soil and should not be allowed to dry out. Mulching in spring can help retain moisture.
• Maintenance: This is a relatively low-maintenance plant. It is best cleaned up in early spring before new growth begins. It is also known for being resistant to slugs due to its thick leaves.
• Uses: It is recommended for mass plantings, border edging, general garden use, and as ground cover in shaded areas.
