Liatris aspera
Liatris aspera is a wildflower that is found in the mid to eastern United States in habitats that range from mesic to dry prairie and dry savanna.
It grows high. The inflorescence is an erect raceme with numerous, purple, button-like flower heads, short-stalked or stalkless, blooming from the top down. It flowers from mid-August through September, with seed becoming ripe in October to November. It can be purchased from specialty suppliers.
Leaves are alternate, numerous, and narrow along the entire stem. The stem is rough with short stiff hairs, and often the leaves are as well.
