Bonamia grandiflora is a rare species of flowering plant in the morning glory family known by the common names Florida lady’s nightcap, Florida bonamia, and scrub morning glory. It is endemic to Central Florida, where there are about 100 known populations remaining, many of which are within the bounds of the Ocala National Forest. The plant has declined in recent decades primarily due to the development of its habitat, which is being converted to urban zones and citrus groves. This is the primary reason that the plant was federally listed as a threatened species in 1987.
This native Florida wildflower is a perennial vine which trails along the ground to a maximum length around 3 meters. There is a deep root and multiple underground stems. The hairy stem is lined with leathery, gray-green leaves up to 5 centimeters long. The inflorescence is a single showy flower borne on a short, erect peduncle. The flower corolla opens in the morning, spreading 7 or 8 centimeters wide and up to 10 centimeters long. It is pale to bright blue-purple with a white throat. At the center of the funnel-shaped corolla are five stamens tipped with yellow anthers. The fruit is a capsule around a centimeter in length containing a few seeds.
