Asclepias (milkweed)
Maine is home to four species of Asclepius, only one of which grows on Mount Desert Island.

Asclepias syriaca (common milkweed) - The early-season flower buds and the very young developing pods are edible after boiling.
   leaves: The leaves are entire (i.e., the margin is neither toothed nor lobed) and their arrangement is opposite (i.e., they grow two at each node on opposite sides of the stem).
   habitat: This native species grows in fields and along roadsides. Donald and Lillian Stokes, in their Guide to Enjoying Wildflowers (p. 232.), reported digging down about six inches from the base of the vertical stem and finding a rhizome, a horizontal, underground stem, about six inches in diameter. As a result of this spreading rhizome, it is common to see many plants growing near each other. A good place to see this species is south of the Maine Coast Heritage Trust building just north of Somesville. If you are lucky, you may see the larva of a monarch butterfly (see image below right).
