Growing delphinium as a cut flower crop can have its challenges, but if you follow an orderly process, it can be a very rewarding flower to grow. Delphinium has several advantages such as its striking, dramatic quality and large stature which can be useful in larger arrangements. It also blooms during that early June window when your spring flowers may be finished, but your summer annuals aren’t flowering yet, helping you fill in that gap. It also provides that hard-to-find true blue color in both light and dark shades.
