Milkweed''s hairy, erect stems grow 2 to 5 feet tall and ooze a milky sap when they are broken. Clusters of fragrant, pinkish-white flowers bloom from June to August. Milkweed is best known for its gray pods, 2 to 4 inches long, covered with soft spines. Evident in late summer and fall, the pods split open to release seeds that lie dormant over the winter and sprout in the spring. Milkweed usually grows in patches in rich, sandy, or gravelly loam soils in fields and along roadways. It is occasionally found in flower and vegetable gardens.
Pull plants while young before they develop extensive rhizomes. Plants will resprout from pieces of rhizome left behind.
