Hydrangea paniculata Diamant Rouge is a stunning new profuse flowering variety which will bring months of colour to your garden - and changing colour at that. Starting out white, the flowers change to pink and ultimately to vibrant red as the season progresses. Winner of the Silver Medal at the 2011 Plantarium, Hydrangea Diamant Rouge is truly a garden gem!
Native to east Asia, Hydrangea paniculata has been grown in the UK for over a century. Hydrangea paniculata Diamant Rouge was bred by Jean Renault in France and is already becoming a garden favourite for the stunning range of colours through the blooming season. The mid to dark green ovate pointed leaves emerge in spring, and then in early July the long flower heads emerge, up to 35 cm across, and are a creamy white, darkening to first a bright pink in August, and then a deep raspberry red by September, remaining on the bush through October. The nectar-rich flowers will attract bees and butterflies to your garden late in the season! The blooms also make excellent long-lasting cut flowers.
Fully hardy in the UK, Hydrangea paniculata Diamant Rouge will grow to a mature height of 1.5 metres and spread of 1.2 metres in 5 to 10 years. In early spring, cut last year’s growth back to within a few buds of woody stem to encourage strong flowering. If planting in a row or group, space plants 1 metre apart.
Plant Hydrangea paniculata Diamant Rouge in full sun or partial shade in an exposed or sheltered position in moist but well-drained humus-rich acid to neutral soil. Once established it is drought-resistant. Tolerant of salt, this colourful bloomer will do well in coastal locations, and is also suited to city gardens as it is pollution-tolerant. Hydrangea Diamant Rouge may need some protection from deer in country settings.
Hydrangea paniculata Diamant Rouge makes an excellent container plant as it can be kept to a manageable size and will reward with a long season of colour. Its hardiness and persistent flowering of this useful shrub lends itself well to border planting, especially when mixed with other flowering or foliage shrubs for a long season of interest. One specimen in a mixed border or as a foundation planting will be a stand-out of the late summer and autumn garden!
Hydrangea paniculata Diamant Rouge will be a valuable addition to your garden - the blooms will provide valuable long-lasting late-season colour when it is most needed!
