Calystegia sepium
of up to 2-4 m, rarely 5
m. The leaves are arranged spirally, simple, pointed at the tip and arrowhead
shaped, 5-10 cm long and 3-7 cm broad.

The flowers are produced from late spring to the end of summer. In the bud,
they are covered by large bracts which remain and continue to cover sepals.
The open flowers are trumpet-shaped, 3-7 cm diameter, white, or pale pink
with white stripes. 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. The seeds disperse and thrive in fields,
borders, roadsides and open woods.
