Family: Asclepiadaceae, Milkweed view all from this family

Description One to several stout, erect stems, 2-3 ft. tall, bear large, domed clusters of pink or pinkish-white flowers at the top or on stalks from leaf axils. Leaves are oval, thick, and somewhat succulent.

Warning All plants in the genus Asclepias are probably somewhat toxic, some fatally so, to both humans and animals. The sap of some causes skin irritation in humans. Sensitivity to a toxin varies with a personís age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plantís different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil.
