Blue mistflower (wild ageratum) is an herbaceous perennial that can grow as tall as 3 feet.
The above ground plant portions grow from colonies of long, slender rhizomes that serves as a storage organ. Leaves are opposite, hairy, oval shaped, and approximately 2 to 3.5 inches long by 1.5 inches wide with toothed edges.
Inflorescences present as large clusters of blue to purple flowers that look similar to cultivated ageratum flowers. The flower clusters are approximately 4 inches in diameter.
Blue mistflowers grow in wet meadows, ditches and along the edges of shallow bodies of water.
