Swamp Rose Mallow features one of the largest flowers of any of the North American natives.  These blooms often are compared to the size of a dinner plate.  It's a show stopper and adds a tropical feel to the garden.
 
     Each bloom lasts a day or two, but subsequent blooms are continuously popping out such that you might have 20 or more blooms on a single plant.
 
     Pollinators also love this plant.  It attracts hummingbirds, butterflies and beetles, and it's a larval host to Delightful Bird-dropping and other moths.
