These Delphinium are stunning! I've heard people say they've had some problems growing these, but this is my first time growing delphiniums and I've had no problems. I planted them in a raised bed and spaced them about 12 inches apart. The soil in the bed is 1/2 peat moss, 1/4 miracle grow potting soil, and 1/4 compost. I live in zone 8a, and they planted in light shade . They get morning sun until 11am, Shade in the afternoon, and then from about 5pm on they get the evening sun. They get water at least every other day, and are mulched well. So far they seem quite happy!
