2 to 3-inch long, stalked, funnel-shaped flowers arising from leaf axils all along the stem. Flowers have 5 petals fused together; petal color ranges from pure white to pink or lavender. At the base of the tube's throat is a spot of yellow, with the stigma in the center. A flower usually lasts only 1 day, opening in the morning and closing in the afternoon, but may stay open all day in favorable conditions.
Leaves and stem:
Leaves are up to 5 inches long and 3 inches across, toothless and hairless, typically arrowhead-shaped with a sharply pointed tip, angled lobes at the base, and a long stalk. Stems are mostly smooth and lack tendrils, so climbs or wraps around other plants for support.
Hedge Bindweed is often seen climbing up shrubs, fences and in open fields. It is similar to Field Bindweed (Convolvulus arvensis), a weedier species with smaller flowers and leaves. Also similar is Low False Bindweed (Calystegia spithamaea), a low-growing, non-vining plant of drier sandy or rocky soil, often in Jack Pine forest.
