Blue mistflower seeds and plants aren't always available in large garden centers
But they can often be found in shops that specialize in North American native species
They also divide well, so you may be able to get some from friends or through plant swaps
If you opt to buy blue mistflower seeds, be sure to sow them in the autumn
so they can experience natural winter seed stratification.
They'll grow best in a space with plenty of moist and fertile soil and at least part sun, though full sun is best.
Blue mistflower is an extremely tough plant, and you can even mow it if you want.
If left alone, it will grow up to 3 feet tall and naturally form clumps thanks to its underground stems
