Hibiscus moscheuto - Swamp Rose-mallow

Ask the Expert: Can you ID this plant?
My niece and I were taking a walk and saw several of these plants, along with black-eyed Susan’s planted around a mailbox. This was in Connecticut, August 1st, if that helps. The yard had many perennials that I was familiar with, but I have no idea what this one is–not even sure if it’s a perennial. Thanks for your help! Mary Ellen

I believe the plant is a Hibiscus moscheutos (Swamp Rose-mallow). It usually blooms July thru September with pink or white blooms (occasionally with red centers). It can grow 4 to 7′ in height and the blooms can be 4 to 7″ across.
