The Best Types of Dahlias to Grow in 2022
Dahlias may be garden classics, but that doesn’t mean they never change. Fresh varieties with different shapes and colors are developed every year. We found the best types of dahlias to grow in 2022.
These new dahlia cultivars may be flashy, but they’re just as easy to care for as traditional dahlias. They’re hardy in Zones 8 to 11. In those zones, the underground roots, called tubers, can stay in the soil over winter. Here’s everything you need to know about growing and planting dahlias.
Outside of Zones 8 to 11, overwinter dahlia tubers indoors in dry sawdust. Cure them in a warm location out of sunlight for a few days and store in a place between 40 and 45 degrees. The tubers may die if it’s too cold or sprout if it’s too warm.
Editor’s note: Because these dahlias are fresh releases, they might not be available in garden centers. The tuberous roots ship well and can be planted in spring. Visit the American Dahlia Society at dahlia.org and Swan Island Dahlias for more new plants and ideas.
