Answer: Liatris can be tricky from seed. Most need a cold stratification period to simulate winter before they will germinate, and often a high percentage of the seeds may not be viable. You can try allowing the plant to set seed and then naturally seed itself in the garden in the fall for spring germination in situ, or you can collect the seed and plant it yourself. Place the seed in a closed container with some barely damp vermiculite and store it in the coldest part of your refrigerator (or even a bit cooler, between 24 to 39 degrees) for about three months, then plant it. Alternatively you could sow the seeds in flats in the fall and store them in a sheltered but cold location over the winter so they germinate naturally in the spring. Good luck!
