Sun Explosion Dahlia - Dinnerplate Flower
Best vibrant focal points for gardeners seeking dramatic floral impact.
Originating from Mexico and Guatemala, Dahlias were the flowers of Inca kings and despite their royal origins Dahlias are among the easiest plants to grow in the garden. They are a wonderful source of cut flowers and will provide a veritable cornucopia of colorful blooms for your bouquets from mid summer until the first hard frost in the late fall. Dahlias are hardy in zones 8 -10. Dahlias are susceptible to cold so be careful not to plant them too early and be sure to dig them up and store them in a frost-free place before old Jack Frost comes calling if you are planting them in a cooler zone! Your new Dahlias tubers can be stored in the refrigerator until planting time or get a head start on spring and start them indoors in a sunny window. Impressively large double flowers displaying a radiant combination of bright-orange and golden-yellow put on a superb show in your summer garden. Blooms lavishly on rigid stems all throughout the summer and fall months. Attains a mature height of close to 32 inches/80 cm. Likes full sun. Electrifying in bouquets.

Know before you buy
Dahlias are not frost-tolerant. If you live in a zone colder than 8, you must dig up the tubers in late fall after the first frost and store them in a cool, frost-free location throughout the winter.
Yes, you can get a head start on the season by planting the tubers in pots and keeping them in a sunny window indoors. This allows the plants to establish roots before you move them outside once the danger of frost has passed.
Sun Explosion Dahlias require full sun to thrive and produce their signature large, vibrant blooms. Aim for a spot in your garden that receives at least six to eight hours of direct sunlight daily.
Absolutely. These dahlias are excellent for bouquets because they grow on rigid, sturdy stems and produce impressive, long-lasting double flowers that bloom from mid-summer through late fall.
When fully mature, this variety typically reaches a height of approximately 32 inches, or 80 centimeters. Their height makes them a great choice for the middle or back of a garden border.
