Ornamental & Landscape Value

Seasonal Interest:

  • Bloom Information: Mid-summer through fall. Conical panicles emerge white, transition to pink, and finish strawberry-red.
  • Fall Colour: Foliage may take on subtle orange or yellow hues.
  • Bark: Smooth, light brown.
  • Fruit/Winter Interest: Dried flower heads remain attractive on the stems through the winter months.

Garden Value:

Perfect for small gardens, large containers, or low flowering hedges. Its compact habit makes it an excellent choice for urban landscapes and tight spaces where larger hydrangeas won't fit.

Wildlife & Human Value:

  • Wildlife Value: Provides nectar for bees, butterflies, and other beneficial pollinators.
  • Human Value: Ideal for floral arrangements; adds significant "curb appeal" and property value; low-allergen garden choice.

Planting & Care Guide

Planting Considerations:

  • Best Time To Plant: Spring or autumn.
  • Spacing: 3–4 feet apart center-to-center.
  • Location Tips: Choose a spot with good air circulation to keep foliage healthy; ensure the site has excellent drainage.

Care:

  • Light Requirements: Full sun to partial shade.
  • Moisture Requirements: Prefers consistent moisture; do not allow soil to dry out completely.
  • Maintenance: Low maintenance. Prune back by one-third in late winter or early spring to encourage larger blooms.
  • Fertilization: Use a balanced, slow-release fertilizer in early spring as new growth emerges.

Tolerances:

Cold hardy; urban pollution; heat (if moisture is consistent); salt.

Tips For Success:

Apply a 2-3 inch layer of mulch to help the soil retain moisture during the heat of summer. Avoid overhead watering to keep the blooms looking their best.
