Hydrangea macrophylla Amethyst

Common Name:
Amethyst Hydrangea

Description:
Hydrangea macrophylla ‘Amethyst’ is a compact, deciduous shrub admired for its large, mophead-style flower heads that display a captivating blend of colours, ranging from soft pinks and purples to hints of blue depending on soil pH. Flowering from late spring through summer and often into early autumn, it provides a long-lasting and evolving display of colour. The blooms gradually age to deeper, antique tones, adding further seasonal interest. Its lush, broad green foliage creates a dense and attractive backdrop, making it ideal for garden beds, borders, and container planting. Well suited to Melbourne conditions, ‘Amethyst’ performs best in part shade with protection from harsh afternoon sun, and prefers moist, well-drained, slightly acidic soil. Regular watering during dry periods and occasional feeding will ensure optimal growth and flowering. Perfect for cottage gardens and shaded outdoor spaces, it also makes an excellent cut flower.
