Delphinium is a group of annuals, biennials and perennials found mainly in mountainous areas worldwide. Most have fibrous or fleshy roots, although some are tuberous. Leaves are approximately 8 in. (20cm) long. They are grown for their showy spikes of colorful summer flowers. The spikes vary in height and shape: those produced by the Belladonna Group hybrids are loose and branched, while the tallest spikes, to 6 ft. (2m) high or more, are produced by hybrids of the Elatum Group. Pacific Hybrids are similar to the Elatum group although not as tall.
