Dogbane Hemp
Apocynum spp. · Apocynaceae
How it looks
Dogbane Hemp is a herbaceous plant that grows in the wild and exudes a white milky sap when its stem is cut. The leaves are oval to egg-shaped and arranged in opposite pairs, and small bell-shaped white-to-pink flowers gather at the branch tips. It stands 12–47 in (30–120 cm) tall, with soft stems and leaves.
Deadly — cardiac arrest
All parts of Dogbane Hemp (Dogbane) contain cardiac glycosides; even a small amount can cause arrhythmias, vomiting, and depression, and in serious cases this can progress to cardiac arrest.
Guide for parents
Dogbane Hemp (Dogbane) is sometimes grown as a garden or ornamental plant, but never bring it into a space where a cat lives. The leaves, flowers, stems, roots, and even the vase water are all dangerous. Don't leave cut stems lying around — dispose of them immediately. If you suspect ingestion, head to a 24-hour animal hospital right away even if there are no symptoms. Cardiac toxicity can appear late, so the golden window is very short.
