These colorful spiky flowers generally bloom from midsummer to first frost, when many other plants are past their best. They range in color and even size, from the giant 5-inch “dinner plate” blooms to the 2-inch lollipop-style pompons.

Don’t be in a hurry to plant; dahlias will struggle in cold soil. Dahlias thrive in rich, well-drained soil. If you have a heavier soil, add in sand, peat moss or bagged steer manure to lighten and loosen the soil texture for better drainage dahlias can be planted 9 to 12 inches apart.
There’s no need to water the soil until the dahlia plants appear; in fact, over watering can cause tubers to rot. After dahlias are established, provide a deep watering 2 to 3 times a week for at least 30 minutes with a sprinkler (and more in dry, hot climates). Bedding dahlias need no staking or disbudding; simply pinch out the growing point to encourage bushiness, and deadhead as the flowers fade. Pinch the center shoot just above the third set of leaves.
This plant is native to the Mediterranean region, Macaronesia (Canary Islands, Azores) and in France in the Bay of Biscay. It is widely naturalized elsewhere in the temperate world.
