Everyone loves this well-named little gem. It’s lack of tolerance for heat is not usually a big problem, since it is so short and blooms so early, the plants are finished blooming before the mid-summer heat kills them and ascending taller plants hide them. The sky-blue flowers are a delight in early seeded meadows, blooming while other wildflowers are still in small seedling stage. See related species, Five Spot, N. maculata.
