Gardeners' Notes:

This pretty, medium-sized shrub grows fast and spreads quickly by underground roots, so it is good as a mass planting. I planted one in my backyard in se PA and it was aggressive and invading the neighboring plants. I removed it after three years and planted it in the wild, but could not find it later, as the open woods were infested with rough strong plants already. It did well in my good clay soil that was neutral pH of 6.9. Its best pH range is 6.5 to 7.5. It blooms in late June - July. It is native to the Mid-Atlantic, down the Appalachians, around the Great Lakes, and up into central Canada.

We have this growing wild on our farm, east of the Ohio Valley. It grows down in an old rock quarry near our little creek and in the fence lines, and is very attractive to butterflies and bees. I have a piece up in the yard and, yes it will spread out, but is easily controlled. I have found it actually less likely to take over than the S. tomentosa

This native American species is very similar to Spirea latifolia, except the flowers are white rather than pale pink. Like S. latifolia, it can be invasive but is useful in a wildflower or butterfly garden. It is also tolerant to wet, acidic soil. It grows mostly west of the Ohio Valley while S. latifolia is mostly east.
