The scarlet hibiscus is a slender shrubby herbaceous perennial that dies back in winter and re-sprouts in spring. Established plants can have one to several stems up to 7 feet tall. The five petaled flowers are brilliant crimson red and 6-8 inches across. Each lasts only a day but new ones continue to open all summer and fall. The leaves are divided palmately (like the fingers on a hand) into 3-7 narrow, pointed, serrated lobes. The scarlet hibiscus occurs naturally in swamps, marshes and ditches, from southern Georgia and Alabama to central Florida. (floridata.com/plants)
