Marsh fleabane is in the Asteraceae, or aster, Family.
Marsh fleabane is a perennial wildflower that grows to a height of 3-6 feet. Some literature states that it is an annual, but I’ve found it to come back from the roots in more than a few instances. It will certainly re-seed where the parent plant was grown.
The leaves are alternate. Their shape is generally elliptic-ovate to lanceolate with toothed margins. The leaves are stalked.
The flowers appear all year except for the coldest part of our winter. The flower heads are tubular and don’t have petals. They are a pretty pale purple.
Marsh fleabane grows in moist areas like wet woods, stream banks, lake margins and other wet areas such as drainage ditches and wet fence rows.
Marsh fleabane is native to AL, AR, CT, FL, GA, IA, IL, KY, LA, MA, MD, MI, MO, MS, NC, NY, OH, SC, TN, TX, and WI.
In the home landscape it grows in full sun to part shade in moist to wet soils. It can be used in a naturalized setting, grown in flower beds, and containers. It transplants relatively well if kept moist once moved.
The flowers are a source of nectar for many insects including bees, beetles, butterflies, flies, and wasps.
