Common Milkweed is a rough, weedy perennial that typically grows 3 to 4 feet tall on stout, upright stems. The plant’s most noticeable features are its spherical umbels of fragrant, pink to purple flowers that bloom from June to August. It is drought tolerant, growing in full sun and in a variety of moist soils, including sandy, rocky, clayey, or well-drained loamy soils. Note that the milky sap from this milkweed is poisonous if ingested in large quantities.
