Title

The Sonic Bloom® series is a true garden revolution, famous for its "humdinger" of a floral display that features waves of vibrant, trumpet-shaped flowers. Whether you choose the lipstick reds, hot pinks, or the pearly whites that age to a soft rose, these blooms nearly hide the lush, emerald-green foliage during their peak. Naturally mounded and vigorous, these shrubs provide a constant, high-energy "sonic" burst of colour that keeps your landscape looking fresh and professionally designed all season long.

Planting & Care Guide

Planting Considerations:

  • Best Time To Plant: Spring or Autumn.
  • Spacing: 60–72 inches apart for hedges or mass plantings.
  • Location Tips: Best in full sun for maximum bloom; highly tolerant of urban pollution and inner-city environments.

Care:

  • Light Requirements: Full sun is essential for the best foliage colour and highest bloom count.
  • Moisture Requirements: Medium moisture; prefers staying consistently moist and should not be allowed to dry out completely.
  • Maintenance: Low maintenance; no deadheading is needed to keep the flowers coming.
  • Fertilization: If desired, fertilize in early spring with a granular fertilizer formulated for woody plants, like a rose fertilizer.

Tolerances:

Clay soil, urban pollution, and deer.

Tips For Success:

Prune immediately after the spring bloom if shaping is necessary to avoid removing the summer and fall flower buds. Rejuvenation pruning (removing 1/3 of oldest branches) every 3–5 years encourages vigorous growth.
