From sunflowers to roses, there are so many gorgeous flowers you can grow in your garden. But few types are as exquisite as dahlias. “Dahlias have such beauty and variety, combined with a long bloom season of up to three months,” says grower Andrew Hunter, of Lynch Creek Farm Dahlias. “With the abundance of flowers and their magnificence in bouquets, they’re fantastic to grow.”
There are tens of thousands of varieties of dahlias, which grow from tubers, in every imaginable color and size. They thrive just about anywhere, except in very hot climates such as Southern Florida and Arizona. In USDA Hardiness zones 8 and warmer (find your zone here), you can leave the tubers in the ground over the winter. In colder climates, you’ll need to dig the tubers up after the first frost has killed the foliage if you want to save them for planting again next spring, says Hunter.
