Gentianopsis crinita
Greater Fringed Gentian
New to me this year, grown from seeds from Ottawa Wildflower Seed and Prairie Moon Nursery https://www.prairiemoon.com/gentianopsis-crinita-fringed-gentian-prairie-moon-nursery.html
Very showy but reportedly particular about location, preferring consistently moist soil conditions. Short lived but known to reseed if they like their growing conditions.
Please check out the Prairie Moon listing at the link above for more details.
