A whimsical and endlessly complementary shade, coral is Barene’s favorite dahlia color for a reason. It adds variety to your garden palette and helps bridge the gap between pink and orange blooms in bouquets. Barene suggests adding Totally Tangerine, Jowey Winnie and Snoho Jojo shades to your cut flower garden.

Similarly, if you’d like a flower in a softer shade than classic bright pink, blush dahlias are an excellent choice. Try to find Coralie, Maltby Pearl and Cafe au Lait varietals to add a gentle touch to your garden. To up the sweetness even more, try planting them alongside your favorite fragrant flowers.

FAQs

Are dahlias a beginner-friendly flower?

Yes, dahlias are easy to care for. Water them just enough so the soil is moist but not sopping wet. Watch for pests, and fertilize dahlias once a month. The only slightly complicated step is when the cold weather hits. “In colder areas, the tubers should be lifted, divided (if necessary) and then stored in a paper bag in a cool, dark spot. They can then be replanted in the spring once the danger of frost has passed,” says Hird.

What growing conditions do dahlias need?

Dahlias prefer well-drained soil and at least six hours a day of full sun. They don’t do well in South Florida and similar hot climates. Dahlias grow best in United States Department of Agriculture (USDA) Plant Hardiness Zones 7 through 10. “USDA hardiness zones are important so that you select plants that will thrive in your growing conditions,” says Hird.
