Growing liatris plants is easy. In addition, these plants effectively handle drought and are fairly tolerant of cold as well. In fact, most are hardy in USDA plant hardiness zones 5-9, with some varieties of liatris hardy in Zones 3 and 4 with mulch.
Then, do Liatris come back every year?
WHEN TO PLANT: Liatris corms are planted in spring, when the weather is cool and it's easy for the young plants to get established. Flowers usually appear the first year, approximately 70 to 90 days after planting, and the plants will rebloom for many years to come.
Just so, does Liatris spread?
The plant spreads slowly, but eventually becomes 3 to 5 feet wide. One plant is usually enough for most garden spaces. Blazing Star self-sows and also spreads through underground roots.
Dig a 6-inch-deep hole for each blazing star corm or rhizome. Space the holes 12 to 15 inches apart in all directions. Set a corm in each prepared planting hole with its flat side on the bottom. Fill in the hole with soil immediately after planting.
