Grow your own dahlias from seed! Burgundy foliage and brilliant single red and orange flowers on 2 1/2-3' tall plants. Ideal cut flowers. You can start seed ahead of time indoors and set the seedlings out after danger of frost is over in late May. Great cut flowers and an excellent foliage accent in the sunny garden. YES, these WILL form tubers that can be lifted and stored for years to come.
