A 2-5 ft. widely branching, bushy, perennial with opposite, oval leaves and small groups of tiny, pink, bell-shaped flowers near the branch tips. The flowers’ fragrance is reminiscent of lilac. Numerous small pink, nodding, bell-like flowers, fragrant and striped inside with deeper pink. Milky juice exudes from broken stems and leaves. These plants are relatives of the milkweeds. Indian Hemp (A. cannabinum), a slightly smaller species with erect clusters of greenish-white flowers, is also found in fields and is poisonous. Clasping-leaved Dogbane (A. sibiricum), found widely throughout the Northeast in sandy or gravelly habitats such as stream banks, has stalk-less or nearly stalk-less leaves.
