HEDGE BINDWEED, Convolvulus
sepium L. 1, plant in flower; 2, seed; 3, seed
pod; 4, variations in leaf shape. Perennial, reproducing by seed
and fleshy creeping rootstocks. Roots extensive but relatively shallow.
Stems smooth, 3 to 10 feet (0.9 to 3 m) long, twining on plants
or trailing on surface of ground. Leaves large, alternate, usually
sharp pointed at tip, basal lobes large. Flowers large, 1-1/2 to
2 inches (3.8 to 5 cm) across, white or pinkish. The flower bud and later
the lower part of the flower and seed pod are enclosed in 2 leafy bracts.
Seed pod about 3/8 inch (9 mm) in diameter, egg-shaped, containing
2 to 4 seeds. Seeds slate-colored to black, dull, usually with 1
rounded and 2 flattened sides. Found in cultivated fields, fence
rows and waste areas, especially on bottomlands. Less drouth-enduring than
field bindweed, but under humid conditions usually a more serious problem.
