Hydrangea paniculata Diamond Rouge® - Diamond Rouge® Panicle Hydrangea

Illuminate your garden with Hydrangea paniculata Diamond Rouge®, a spectacular variety that offers a festival of colours throughout the season! Its abundant flower heads transition from pure white to soft pink, then to an intense raspberry red, finally settling into a rich wine red. This compact, easy-care shrub is a true focal point, promising a dazzling display from July through autumn.

Characteristics

• Foliage: Dark green leaves, providing a beautiful backdrop for the flowers. In fall, the foliage transforms into a magnificent dark orange, adding seasonal interest. The foliage is deciduous (falls in winter).
• Flowering: Produces abundant, long-lasting, rounded flower heads that start white, progress to pink, then intense raspberry red, and finally a deep wine red. Blooming begins in July and takes on red coloration earlier in the season than other pink panicle hydrangeas.
• Light Requirements: Tolerates full sun to part shade. Full sun exposure generally promotes better flower colouration.
• Habit: Compact and upright habit, forming a well-structured shrub.
• Growth: Moderate growth rate. Reaches a mature height of approximately 120 to 150 cm (4 to 5 feet) and a spread of 90 to 120 cm (3 to 4 feet).
• Humidity: Requires medium watering. Once established, it is drought tolerant.
• Soil: Adapts well to most garden soils, provided they are well-drained.
• Temperature: Very cold hardy. Tolerates winter cold well. Its fall colour is best when night temperatures are 10 degrees cooler than day temperatures.
• Watering: Medium watering. Although it tolerates drought once established, regular watering is beneficial, especially during intense heat periods.
• Resistances: Drought tolerant. Generally resistant to diseases and pests.

Usage

• Types of Use: Ideal as a focal point in garden beds, as a small hedge, or in containers for patios. Its flowers are excellent for fresh or dried cut flower arrangements.
• Decorative Benefits: The spectacular colour evolution of its flowers, from white to deep wine red, offers prolonged visual interest from mid-summer through autumn. The fall foliage colour beautifully complements the display.

Maintenance

• Fertilization: Fertilize in spring with a balanced NPK fertilizer to promote healthy growth and generous flowering.
• Pruning: Prune in early spring, before new growth appears, to maintain shape, control size, and encourage abundant flowering. It blooms on new wood.
• Planting:
  • Spacing: Approximately 90 to 120 cm (3 to 4 feet) apart to allow for good development and air circulation.
  • Depth: Plant at the same depth as it was in its container.
  • Period: Spring or early fall are the best times for planting.
