| Distribution | Mountains and upper Piedmont.
Native of China, Korea, Japan; in N.A. -- N.S. to Ont. and WI, south to GA and MO; UT, CA. | |
| Abundance | Now fairly common to locally common in the Mountains, and spreading fairly rapidly there. Scarce in the upper Piedmont. | |
| Habitat | Roadbanks, open or disturbed woods, and old homesites. This can be a highly invasive species, growing well in shade and impacting native herbs and shrubs in the Mountains. | |
| Phenology | Flowering May-August. | |
| Identification | Japanese Spiraea is a small shrub, up to about 4 feet tall. Leaves are elliptical and taper to both ends, sharply toothed. Flowers grow terminally in a rather flat-topped to somewhat rounded clusters, pale to dark pink -- easily spotted at a long distance, as there are very few shrubs or tall herbs with bright rose-pink flower clusters in the mountains. | |
