Care Guide

Ornamental & Landscape Value

Seasonal Interest:

  • Bloom: Electric blue (acidic soil) or pink (alkaline) lacecap flowers from early summer to mid-fall.
  • Fall Colour: Insignificant change; green leaves drop in late fall.
  • Bark/Evergreen Interest: Woody stems provide winter structure.

Garden Value:

A premier choice for compact spaces, including patio containers, low hedges, and front-of-the-border mass plantings. Its small stature makes it ideal for modern foundation plantings.

Wildlife & Human Value:

  • Wildlife Value: Unlike many sterile cultivars, Pop Star® is specifically noted for being a good choice for attracting bees and butterflies.
  • Human Value: Provides long-season colour for small balconies and high-impact curb appeal with minimal pruning required.

Planting & Care Guide

Planting Considerations:

  • Best Time To Plant: Spring or fall.
  • Spacing: Plant 3 feet apart for a continuous border.
  • Location Tips: Ensure a sheltered location away from harsh winter winds and strong afternoon sun.

Care:

  • Light Requirements: Thrives in partial shade; ideally morning sun and afternoon shade to prevent leaf scorch.
  • Moisture Requirements: Needs consistently moist, well-drained soil; do not allow to dry out completely.
  • Maintenance: Low to medium; prune only after flowering to avoid removing next year's buds.
  • Fertilization: Feed with a balanced 10-10-10 fertilizer in early spring and again in early August to boost reblooming.

Tolerances:

Tolerates urban pollution and cold temperatures down to Zone 4.

Tips For Success:

Apply a 3-inch layer of organic mulch to conserve root moisture. For blue flowers, add aluminum sulfate; for pink, use garden lime.
