Spreading Dogbane, a native perennial, reaches a height of one to four feet. The flowers appear in groups of two to 10. They are about 1/4 inch wide, bell-shaped, and white with pink stripes. Five petals fuse together to form the bell. The plant has simple, oval, toothless leaves that are two to four inches long, often with wavy edges. It grows in dry, sunny areas along roads and deciduous woodland edges. (LS)
