Spiraea japonica 'DART'S RED'

Bumalda spiraea is an attractive version of Japanese spiraea, a garden cross between spiraea albiflora and spiraea japonica. In spite of this interspecific crossing the nomenclature classifies the plant as s.japonica, leaving s.x bumalda as a synonym only. We stick to this older version because it differs this hybrid from other Japanese spiraeas mainly in lower growth, more compact habit, and coloured emerging foliage.

Dart’s Red is an eye-catching Bumalda spiraea with deep pink flowers. They are formed in terminal corymbs from June until late summer if deadheaded continuously. Leaves are narrowly elliptic, coppery red when they emerge, turning dark green in summer, shallowly serrated at margins. When in full bloom the inflorescences are held just above foliage making a stunning display of pink flowers. A sport of Anthony Waterer spiraea.

Spring pruning will encourage new growths and the plant will get thicker and will flower more profusely. You can cut off up to two thirds of previous year’s growth or trim the twigs to achieve a desired shape. It is widely soil adaptable but does best in slightly acidic, fertile, constantly moist soil in full sun. Fully hardy to about -40°C (USDA zone 3) and suitable for outdoor pots.
