Save the flowerhead/seed stalk. In late fall, make a small trench in the garden, a little less than an inch deep and lay the flowerhead/seed stalk in the trench. Cover lightly with soil. Next spring, you will have baby liatris.
These estimates for how long Liatris takes to sprout, grow and harvest are from real observations from real gardeners, right around the world.
