Rose mallows are usually found in moist, sunny areas but on occasion they can be found in shady, moist areas, too.
The seeds can be roasted then ground in a coffee grinder for use as a substitute for real coffee. It tastes pretty good, though does not have any caffeine.
Young tender leaves can be cooked like spinach but I find them a bit too rough/stiff to use raw. The flowers are good raw or added to tea. The tender, young flower buds and seed pods can be used like okra, either friend, pickled, or added to Cajun and African foods. The flowers work well in salads.
