Flowers are funnel-shaped, 2 to 3 inches long, usually white, occasionally pink. The 5 petals are fused at the base and form 5 shallow lobes at the tip end. Inside the tube is the white stigma. A plant typically only has a few flowers, short stalked and arising from leaf axils on the lower stem, usually only 1 is open at a time and lasts a single day.
Leaves and stems:
Leaves are 1 to 3 inches long, toothless, more or less hairy, generally oblong-elliptic, rounded or pointed at the tip, rounded to somewhat heart-shaped at the base, and short stalked. Stems are hairy and mostly erect, sometimes drooping at the tip and sometimes twisted, but not twining.
While the large funnel-shaped flowers are similar to the more common Hedge Bindweed (Calystegia sepium), Low False Bindweed's low growth habit, non-twining stem, and usually drier habitat easily distinguishes this species.
