Hydrangea Serrata Blue Deckle

Common Name:
Mountain Hydrangea 'Blue Deckle'

Description:
Hydrangea serrata 'Blue Deckle' is a compact deciduous shrub renowned for its delicate lacecap blooms and vibrant autumn foliage. The frilly, serrated-edge flowers range from pale blue in acidic soils to soft pink in alkaline conditions, offering gardeners the opportunity to influence bloom colour through soil pH. Flowering from late spring through summer, the blooms gradually transition to sea-green with lilac undersides as they age, providing extended visual interest. In autumn, the foliage transforms into striking shades of red and purple, enhancing seasonal appeal. Ideal for Melbourne gardens, 'Blue Deckle' thrives in partial shade with moist, well-drained, humus-rich soil. Its compact size and ornamental features make it suitable for borders, woodland gardens, or container planting.
