This plant is more commonly known as Shooting Star, but it has several other common names, e.g. Roosterheads and American Cowslip (which is also the title of a movie about a heroin addict who has a flower garden).
It is one of the more attractive plants in a prairie. It blooms earlier in the year before becoming overwhelmed by the grasses and other tall plants. It is also planted in gardens a lot since it is so beautiful.
It’s genus name, Dodecatheon, comes from the Greek meaning “Twelve Gods”. Why Linneaus gave it this name is widely speculated, but I think you’d have to ask Linneaus to know for sure.
