spreading dogbane, Apocynum androsaemifolium
Spreading dogbane is a plant of open land, standing two or three feet tall. The flowers are about a third of an inch long. It is a milkweed realative, and has similar pods with wind dispersed seeds. The stem fibers were used for cordage. It contains the same toxic chemicals as milkweed, in even greater concentrations. It does not appear to host monarch butterflies, who may find it too much of a good thing. It grows in every state except FL, HI, KS, LA, MS, OK, and SC, and in every province except LB.
