Sub-category: Morning glory family
An herbaceous perennial that twines around other plants, in a counter-clockwise direction, to a height of up to 2 to 4 m, rarely 5 m. The pale matte green leaves are arranged spirally, simple, pointed at the tip and arrowhead shaped, 5 to 10 cm long and 3 to 7 cm broad. The flowers are white, or pale pink with five darker stripes. In the bud, they are covered by large bracts which remain but scarcely overlap and do not cover the sepals of the open flower. The open flowers are trumpet-shaped, 3 to 7 cm diameter. After flowering the fruit develops as an almost spherical capsule 1 cm diameter containing two to four large, black seeds that are shaped like quartered oranges.
Found in fields, borders, roadsides and open woods. Blooms late spring to the end of summer.
