Common Wingstem is a native perennial found
throughout most of Alabama. Its preferred habitat is moist sunny
sites such as along streams, the edge of mesic woodlands, and
roadside ditches. It grows from three to eight feet in height.
The plant produces short rhizomes, often giving rise to clusters
of flowering stems.
The leaves are alternate on the stem and
winged; broadly elliptic, petioled, 6 inches or longer. The upper
stem leaves are essentially sessile and about 3 inches long,
linear-lanceolate; rough above and below.
The flowers are produced in heads about
1/2 inch in diameter. Both the ray and disc flowers are yellow.
The ray flowers tend to droop downwards.
Fruit is achene with a winged margin and
two horn-like awns at its apex.
