Delphinium is a genus of perennial flowering plants in the family Ranunculaceae, known for their tall spikes of vibrant blue, purple, pink, or white flowers. The name Delphinium comes from the Greek word "delphis," meaning dolphin, due to the shape of the flower buds resembling the nose of a dolphin.

Delphiniums are commonly grown in gardens and used in cut flower arrangements. They prefer full sun to partial shade and well-draining soil. They require regular watering and benefit from the use of a balanced fertilizer.
