I have many different species of plants in my landscape. However, I do not own a “Clethra alnifolia” or “sweet pepper bush” or “summersweet”. I bet if I were to ask brother Rufus if he planted one in his historic yard, he would say yes. Clethra is a native plant to Eastern North America including North Carolina of course. My expert friends on the Weekend Gardener tell us that Clethra is a choice shrub for the Tar Heel state’s growing conditions.
