Comments

Blooms May-November. Species name linearis referes to the linear leaf shape. The common name comes from the overall slim appearance of the plant. Similar to Whorled MIlkweed (Asclpeias verticillata) but the leaves are not arranged in a whorl. Nectar source to butterflies, bees, and wasps. Larval host to Queen and Monarch butterflies.
