  • Blackmore and Langdon Hybrids - Flower colors include white, cream, yellow and blue.
  • 'Connecticut Yankee' - 30 inches, free-flowering, densely branched, with an excellent color range.
  • Dwarf Pacific Hybrids - Only 2 feet tall and often treated as annuals. Two selections are 'Blue Fountains' (mixed blues) and 'Blue Heaven', sky-blue.
  • Giant Pacific Hybrids - This seed-grown hybrid has colors of blue, violet, purple, pink, white and lavender. Most of the flowers are double.

Delphinium is derived from the Greek word delphis meaning dolphin and refers to the flower buds before they expand which resemble dolphins.

Delphiniums at best are short-lived perennials that either die or lose their vigor after 2 or 3 years.
