Virginia Sweetspire (Itea virginica) is a structural shrub with white blooms in summer. They prefer wet to mesic soil in sun to part sun where they grow up to 5 feet tall. They are a good choice for slopes and basins. Companion plants include Palm Sedge (Carex muskigemensis) and Southern Blue Flag Iris (Iris virginica shrevei).
Remove suckers as needed throughout the growing season and prune out any dead wood.
