Hibiscus thrives in summer heat. It provides a bold display of showy green and scarlet foliage on sturdy stalks marbled with the same colors. In late summer, pink blossoms emerge, opening in the morning and closing again in the evening. The fleshy, deep red calyxes can be picked and dried for a tangy, refreshing tea that has been said to contain high amounts of antioxidants, vitamin C, and antimicrobial properties.
