This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.
Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.
This plant is widely used in gardens. Although it has been extirpated in parts of its range, garden escapes have led it to establish in new places elsehwere. We mark new populations expanded because they are relatively close to its native range.
↑Habitat
Found in a variety of sunny, wet habitats, especially ones that alternate between wet and dry conditions, including wet meadows, sunny portions of floodplains, margins of marshes or bogs, fens, seeps in rock outcroppings, and areas where hardpan soils of clay or fine silt alternate between waterlogged and dry conditions. This species is uncommon to rare throughout much of its range, but can be locally abundant in some places where it occurs. Also occasionally found in anthropogenic habitats including along railroads, especially in habitat fragments resembling marshes or wet praries where it would naturally occur.
Tolerates a wide variety of soil textures, but is not competetive in loamy soils. Usually found in sandy soils, hardpan clay, or cracks in rock outcroppings.
This species prefers wetter habitats than most Liatris species.
↑Uses
This species is widely cultivated, and in most of its range it is much more common in gardens than in the wild.
↑Notes
Some sources also refer to this plant as having a common name of "button snakeroot"; we do not recommend using this name because it more frequently refers to rattlesnake master (Eryngium yuccifolium), a plant that is not closely related. The other common names of dense blazing star, gayfeather, prairie feather, and marsh blazing star, listed roughly in order of frequency of use, all unambiguously refer to this species.
