Common Name: Delphinium
Botanical Name: Delphinium elatum (del-FIN-ee-um ee-LAY-tum)
Decorative Life: 4-12 days.
Post Harvest Care:
  • Remove bottom leaves if present, recut stems under water and place into a fresh flower food solution. Sugar in the flower food can delay ethylene production and decrease the flower's sensitivity to ethylene.
  • To restate, make sure that they are treated with an anti-ethylene product properly. This is a good flower to use the "apple test" on as described elsewhere in this Internet site.
Family Roots:
  • Member of Ranunculaceae (buttercup family).
  • Native from Europe to Siberia.
  • Common relatives include columbine, larkspur, monkshood and anemone.
  • Height from 4-8 feet.
  • Single or double flowers occur on unbranched spikes.
  • Plant is classed as a dicotyledon, leaves not parallel veined.
  • Flowers are not fragrant.
Availability: Year-round, peak in spring.
Flower Color: Shades of blue, white, pink and even red.
Storage Specifics: 32-36 degrees F based on best available data.
  • Delphinium’s petals have been said to resemble the bottle-nose of the dolphin, hence the Greek derivative of the name “delphis,” which means dolphin.
  • As a garden plant, it is often plagued by lack of hardiness, insect and disease problems. This species is an important parent of many garden hybrids and therefore is often named D. x elatum where the x means it is a cross of different species.
  • Plant parts are poisonous, ingestion may cause illness.
  • Good vertical accent.
  • Make sure stems are rinsed in tap water prior to cutting under water to remove excess debris that could clog the stems.
Recent Findings: Ichimura et al. (2000) determined that the most abundant sugar in delphinium is mannitol, not the more common glucose, fructose or sucrose. In fact, treating this species with a flower food containing mannitol delayed the abscission of flowers by reducing the plant's sensitivity to ethylene.
