About Japanese spirea
Spiraea japonica, commonly known as Japanese spirea, is a medium-sized deciduous shrub, valued for its abundant summer flowering. Its small flowers, ranging from pink to red, are grouped in terminal corymbs, creating a visual spectacle. It is ideal for borders, mass plantings, or as a standalone specimen in low-maintenance gardens.
Native range
East Asia (Japan, China, and Korea)
Care tips
It prefers full sun exposure for optimal flowering, although it tolerates partial shade. Watering should be regular during the first year and in dry periods, but once established, it is quite drought-tolerant. It adapts to most well-drained soils, with slightly acidic to neutral substrate being ideal. A common mistake is not pruning the plant annually after flowering to encourage compact growth and more vigorous blooming the following year.
