More Information:

Leaves, fruits, and stems are toxic. Caterpillars of monarch butterflies feed on and sequester toxins from milkweed plants.

The genus Asclepias is named for the Greek god of healing, Asklepios. The species name tuberosa is from the Latin and refers to the fact that the rhizomes of some plants have tubers.
