Japanese Meadowsweet, Japanese Spirea
Ubiquitous in gardens, Japanese spirea is a small upright deciduous shrub native to eastern Asia. This hardy, easy to grow, densely mounding plant bears many soft flat clusters of pink flowers from early to late summer. The toothed oval medium-green leaves sometimes turn bright colors in fall. Many cultivars are widely available including the golden-leaved 'Goldflame', and the rose-pink-flowered 'Little Princess'.
Tolerant of light shade and a wide range of soils, Japanese spirea is a highly versatile ornamental shrub that works well in mass plantings, mixed borders, and low informal hedges. Deadhead spent flowers to encourage prolonged secondary bloom. Prune back plants to a hand's-breadth and remove weak and dead stems in early spring to promote strong healthy new growth and larger more abundant flower heads. This plant often self-sows prolifically and is considered invasive in some regions.
