Overview
Spiraea japonica 'Goldflame' is a compact deciduous shrub reaching 3-4 feet (0.9-1.2 m) tall with a spread of 3-4 feet (0.9-1.2 m), developing a dense, rounded, mounding form. The primary ornamental feature is the color-changing foliage: new growth emerges bronze-red to copper-orange in spring, matures to golden-yellow with greenish tones in summer, and turns coppery-orange to russet in fall. Leaves are alternate, simple, ovate to lanceolate, 1-3 inches (2.5-8 cm) long, sharply serrate. Flowers are rosy-pink, tiny, borne in flat-topped terminal corymbs 3-5 inches (8-13 cm) across in June to August. A second, lighter flush of bloom may occur if spent flowers are removed. Growth rate is moderate at 6-12 inches (15-30 cm) per year. Classified as potentially invasive in some areas of the Pacific Northwest; Spiraea japonica is listed as a noxious weed in several states. Monitor for seedling spread and remove seedlings. Foliage color is most vivid in full sun; plants in shade tend toward green with less color variation. Occasional green-leaved reversions may occur; remove these promptly as they are more vigorous and will overtake the colored foliage.
Native Range
The species Spiraea japonica is native to Japan, Korea, and China. The cultivar 'Goldflame' is a garden selection. The species is classified as invasive in parts of the Pacific Northwest and eastern North America.Suggested Uses
Planted in mixed borders, foundation plantings, and mass plantings where the color-changing foliage provides season-long interest, spaced 3-4 feet (0.9-1.2 m) apart. The golden foliage contrasts effectively with purple-leaved plants (Physocarpus opulifolius 'Diabolo', Sambucus nigra 'Black Lace'). Low informal hedging. Monitor for invasive spread — check local noxious weed lists before planting. Suitable for containers (minimum 7-gallon).How to Identify

Care & Maintenance
Care Guide
Water regularly during the first growing season. Established plants are moderately drought-tolerant. Plant in full sun for the most vivid foliage color; part shade is tolerated but produces less colorful, greener foliage. Tolerates a wide range of soils. Deadhead spent flower clusters to promote rebloom and prevent seed set (important given the species' invasive potential). Remove any green-leaved reverted shoots promptly at their point of origin. Monitor for and remove seedlings in garden beds.Pruning
Prune in late winter (February through March) before new growth. Cut back by one-third to one-half to maintain compact form and promote vigorous new growth with the best foliage color. Can be sheared to a formal shape. Remove dead and twiggy interior growth. Remove green-leaved reversions at any time. Deadhead spent flower clusters during the growing season. Rejuvenate overgrown plants by cutting to 4-6 inches (10-15 cm) from the ground in late winter.Pruning Schedule
