The leaves are round, smooth, green, leathery and have a slit on one side. The underside is often red or purplish with numerous veins. The leaf stalk is attached to the leaf center at the base of the slit. The flowers are large and fragrant. They can be white, pink, or purple petals with a yellow center.
Concern: They can form dense colonies that can impede recreational activities such as fishing, boating, and swimming.
