Liatris punctata
Also called Dotted Gayfeather, Plains Gayfeather, Plains Blazing Star, Snakeroot, Nebraska Gayfeather, Dotted Blazingstar
Liatris punctata is a species of flowering plant in the family Asteraceae known by the common names dotted gayfeather, dotted blazingstar, and narrow-leaved blazingstar. It is native to North America, where it occurs throughout the plains of central Canada, the central United States, and northern Mexico.
This species is listed in the U.S. Forest Service Fire Effects Information System (FEIS) as being good for revegetating prairie habitats and reclaiming mining spoil. Dotted gayfeather is highly recommended by wildflower writers such as Claude A. Barr as ornamental plant for its clear spires of purple blooms even in dry years due to its substantial water storing taproot. In climates with more moisture than its native range, it needs lime or potash additions to soil to maintain stiff, upright stems.
This plant occurs in Canada from Alberta to Manitoba, in most of the central United States and part of Mexico. There are three varieties, with var. punctata in western areas, var. nebraskana more common to the east, and var. mexicana in Oklahoma and Texas.
