Delphinium Trivia Questions

Pacific Giant hybrids can reach 6–8 feet tall, thanks to their robust root systems and rapid growth in cool climates.

Delphinium contains alkaloids like delphinine that can cause severe poisoning if ingested, affecting the nervous system.

Delphiniums are members of the Ranunculaceae (buttercup) family, not orchids. Their shape attracts pollinators but they aren't mimics.

Unlike hydrangeas, delphinium color is determined by genetics, not soil pH. Their blues and purples are stable regardless of acidity.

The unopened flower bud looks like a dolphin’s nose, leading to the name from the Greek 'delphis' meaning dolphin.

The crushed seeds or leaves were applied externally as a parasiticide, due to the toxic alkaloids that kill lice and mites.

Delphiniums are found across the Northern Hemisphere, including North America, Europe, and Asia—not just the Mediterranean.

While some seeds have long dormancy, delphinium seeds typically remain viable for only 1–3 years under normal conditions.
