Whorled milkweed Asclepias verticillata
IDENTIFICATION — This 2-ft.-tall perennial weed spreads by roots and seeds. A white sap oozes when the leaves or stems are broken or cut and long, narrow, pointed seed pods are produced in summer.
FAVORITE CONDITIONS — You’ll spot whorled milkweed in areas with full sun and well-drained soil, such as meadows or other grassy areas that are not frequently mowed.
CONTROL — Dig the plants or use a herbicide in early summer.
