I was just looking through the book of The Living Landscape by Rick Darke & Doug Tallamy, concerning native plant - naturalistic landscapes, and there are two wonderful photos of this shrub in white bloom on page 195 and it looks good. It reminds me of the Vanhoutte Spirea or Bridalwreath. Mr. Darke uses it on this property as part of the shrub border, a deer-proofing screening shrub, and as a woody plant cut flower. It was first discovered in Alabama in 1857. It has been further found not just in two areas of northern Alabama but also in spots in Mississippi, Arkansas, southern Tennessee, and Georgia, and one spot in southeast Missouri. It has simple, double-toothed leaves that turn greenish-yellow to yellow in autumn. It bears erect clusters of flowers without petals, but with numerous, showy, feathery, white stamens in late April into May. It grows about 1 to 1.5 feet/year. It has a fibrous root mass that makes it easy to transplant, and it can be divided like a perennial. I took photos of a shrub in a pot at a native plant sale in northern Delaware by the Delaware Native Plant Society. The Mount Cuba Center in northern Delaware has some good plantings. Jenkins Arboretum in Berwyn in southeast Pennsylvania has a few plants along a main path, though a little too shaded, and has a bigger group on a slope just outside its perimeter fence that get more light than the smaller group and blooms better. Snow-wreath makes a better bloom in sunny locations. Morton Arboretum in northern Illinois has some listed as planted on their grounds.
