Prairie Sky Hosta

Prairie Sky Hosta (Hosta 'Prairie Sky')

Prairie Sky Hosta forms a refined mound of cool, powdery blue foliage that holds color well through summer; slender scapes rise in midsummer with pale lavender bells, bringing vertical accent to shaded beds and containers.

Distinctive Features

Thick, heart-shaped leaves carry a persistent blue bloom for strong contrast in shade, while the plant�s tidy, medium-size habit fits pathways, pockets, and mixed woodland plantings.

Growing Conditions

Plant in rich, evenly moist, well-drained soil with morning sun and afternoon shade to preserve blue coloration and leaf substance.

• Sun Exposure: Partial shade to bright dappled light; brief morning sun is beneficial, avoid hot afternoon sun.
• Soil: Moist, well-drained, humus-rich soil; amend clay with compost for aeration.
• Water: Moderate and regular; do not allow extended dry periods, especially in containers.
• USDA Hardiness Zones: 3 to 9.
• Mature Size: About 14 to 18 in tall and 24 to 30 in wide.
• Bloom Time: Midsummer, pale lavender flowers on slender scapes.
• Soil pH: Slightly acidic to neutral, about 6.0 to 7.2.

Ideal Uses

• Focal Point: Blue leaves provide striking contrast in dim sites.
• Edging: Neat mounds define shaded beds and paths.

Low Maintenance Care

Consistent moisture, seasonal grooming, and mulch keep plants lush and clean through heat and storms.

• Watering: Deeply soak when the top 1 in is dry; increase frequency during hot spells and in pots.
• Pruning: Remove spent scapes after bloom and trim tattered leaves; cut back foliage after frost.
• Fertilizing: Top-dress with compost in spring; apply a balanced, slow-release fertilizer if growth is light.
• Mulching: 1 to 2 in of shredded bark or leaf mold, keeping mulch off crowns.
• Notes: Monitor for slugs and snails; use traps or iron phosphate baits and avoid late-day overhead watering.
