Is this mountain laurel or rhododendron? Seems no one is sure. Grows in USDA hardiness zone 7b. Lower shrub limbs laying on ground typically take root and extend growth area. Plants easily make it to 6 ft (2m) height if not pruned. Blooms in April/May each spring in our area. Plants are located in partially shaded area under trees and require little to no care other than pruning from time to time.
Why am I asking now? Thinking about giving some to my son and he has very rocky infertile ground. From what I have read that sounds great for mountain laurel and not so much for rhododendron.
