November 2025Spiraea Japonica | Japanese Spirea
Spiraea Japonica (Japanese Spirea) is a deciduous shrub native to China and Japan where it can be found growing on woodland borders, slopes, rocky hillsides, and riverbanks. It is a fast-growing shrub that is well known and desired across North American gardens.
It is a mounded shrub creating a dense network of wiry stems. Sharply toothed and ovate in shape, the foliage of this shrub is lush and bright green. In the spring, flowers emerge in colors of white, light pink and bright pink. It flowers profusely, with flower clusters almost completely covering the foliage, creating gentle, pinky cushion-like mounds in the garden. Pollinators are particularly attracted to this impressive flowering.

It also contributes beautifully to a mixed hedge but take note to prune regularly to keep the plant tidy and contained.
In the eastern United States, Spiraea Japonica easily escapes garden settings and naturalizes in a variety of ecosystems, and outcompetes native plants. It is listed as invasive in many states of the southeast such as Kentucky, Tennessee, Georgia, and South Carolina.
Landscape Uses and Maintenance - Spiraea Japonica
It is easily grown in full sun with average soils and prefers alkaline soils that are well-drained. However, some light shade will be tolerated. Since this shrub only flowers on new growth, it is important to prune in late winter to ensure ample new growth for next seasonâs flowering. It grows quickly and can be aggressive. It is a suckering and easily self-seeds, and will spread to form dense thickets if not pruned or controlled.
It can be susceptible to a variety of pests and diseases like mildew, leaf spot, and aphids, which are also common ailments of other Rose family members. While they can be susceptible to some pest and disease, they are robust and relatively easy to grow.

How to Grow and Care for Bare Root Shrubs
Bare root shrubs are a budget-friendly and efficient way to plant during the cooler months when they’re dormant. Before planting, soak the roots in water for 3–6 hours to rehydrate them. Choose a site with the appropriate light exposure for the species—most flowering shrubs prefer full to partial sun. Dig a hole wide enough to spread out the roots and deep enough so the crown (where the roots meet the stems) sits level with the soil surface.
Mound a bit of soil at the bottom of the hole, spread the roots over it, and backfill with native soil while gently firming it to remove air pockets. Water deeply after planting to settle the roots. Keep the soil moist but not soggy during the first growing season to encourage healthy establishment.
Mulch around the base (not touching the stems) to retain moisture and suppress weeds. Prune lightly to remove any broken branches and to shape after the first flush of growth. With minimal care, bare root shrubs will leaf out beautifully and grow into reliable, long-term landscape anchors.
