Astilbe × arendsii 'Color Flash' - 2026

Astilbe × arendsii 'Color Flash' is a striking perennial valued not only for its feathery plumes of soft pink flowers in early to mid-summer but also for its unusually colourful foliage. The leaves emerge green before maturing to shades of bronze, red, and purple, adding a dynamic element to borders and shaded gardens long after flowering has ended. Its compact size and multi-season appeal make it a versatile choice for mixed plantings or as a feature in containers.

Preferring partial to full shade, it thrives in moist, fertile soil that is rich in organic matter. Consistent watering is essential, particularly during warm weather, as astilbes are intolerant of drying out. Once established, it requires little maintenance apart from removing spent flower stems to maintain a tidy appearance.

This cultivar is especially effective in shaded garden beds, woodland-style plantings, and alongside ponds or streams where soil remains consistently damp. Its nectar-rich flowers attract pollinators, while the bold foliage provides season-long structure and colour in low-light areas.
