Spotted Joe-Pye Weed

Eupatorium maculatum

John Haarstad

Spotted Joe-Pye Weed is a tall plant, growing up to six feet tall. It has a flat-topped cluster of fuzzy pink or purple flowers and purple stems.

There are several species of Joe-Pye weeds, supposedly named after an Indian who used it as a medicine.

Spotted Joe-Pye Weed grows in fields and thickets, and also along shores of streams, ponds, and marshes. This plant often grows in thick stands. A stand is a large group of the same plant growing close together.

Spotted Joe-Pye Weed leaves grow up to eight inches long. They are thick and green with teeth on the edges. Between three and five leaves will branch out from the same spot on the plant's stem. This is called a whorl of leaves.

Flowers are small, only 1/3 inch wide, but they bloom in large clusters over five inches wide. Spotted Joe-Pye Weed blooms from July to September.

Spotted Joe-Pye Weed also has underground stems, called rhizomes, which grow sideways and send up new plants. This is how Joe-Pye Weed can start a colony and form a stand. This plant is a perennial, so the above-ground parts die in the Winter and the rhizomes start new stems, leaves, and flowers the following year.

Many insects are attracted to the nectar of Spotted Joe-Pye Weed, including bees and butterflies. These animals help the plant by pollinating it. This allows it to make fruits and seeds so new plants can grow.

Spotted Joe-Pye Weed is often found growing alongside sedges, bulrushes, cattails, thistles, Queen Anne's Lace, jewelweed, ironweed, and goldenrods.

The seeds of this plant are eaten by White-footed Mice, Mallards and Wild Turkey. Plants are eaten by Eastern Cottontail and White-tailed Deer.
