Growing up right next to garden wall near side of house through small landscaping rocks, about 8 inches tall, flower smaller than pinkie nail, stem and leaves hairy opposite leaves, about 10 in area (DNC, wilted)
Woody, waist to shoulder high underside of leaves is lighter that top, inside of flowers looks thick (Roufs 44) looks like it might be spreading dogbane but the picture quality makes it difficult to tell for sure
