Delphinium is a genus consisting of over 300 species of annual, biennial and perennial flowering plants. Most delphiniums sold in commerce today are complex hybrids. One such hybrid grouping, commonly known as English hybrid types or Elatum Group (often designated as Delphinium x elatum), features a large number of showy cultivars which have been introduced into commerce over time in a number of different series or strains which are considered by many gardeners to contain some of the showiest of the delphiniums available in commerce today.
