Rose of Sharon
Hibiscus syriacus
A tough shrub that brings big, tropical-looking flowers in late summer, when few shrubs bloom, and takes heat, salt, neglect and most soils; it makes a good flowering hedge. It reseeds heavily if not deadheaded, and it's reported invasive in some states, including Virginia and Kentucky.

Spacing for a hedge

Place a row in your own yard and VeraScape spaces them at their mature width, so you can see whether they’ll crowd the walk.
