Larkspur is commonly known as Delphinium, a genus of over 300 species of flowering plants in the buttercup family (Ranunculaceae). Delphiniums are recognized for their striking and vibrant flower spikes that can reach impressive heights, making them a popular choice in gardens for their ornamental value. They typically bloom in shades of blue, purple, pink, or white, with the tall spires creating a dramatic effect in landscape designs.

This identification is particularly important for horticulturists and gardeners, as each plant has unique care requirements and growing conditions. Understanding that Delphinium is the correct name for Larkspur helps ensure that one applies the appropriate horticultural practices, such as selecting the right planting location based on sunlight, soil type, and moisture needs.

In contrast, coneflower, fuchsia, and spurge refer to entirely different plants with distinct characteristics and uses, thus reiterating the importance of proper plant identification in horticulture.
