Identifying Features
To distinguish between different types of delphiniums, focus on key features such as plant height, flower color, leaf shape, and bloom time. These characteristics can help you identify the specific variety or hybrid you are growing or considering for your garden.
Plant Height
Height is one of the most noticeable features. Tall varieties typically grow 4-6 feet, with some reaching up to 8 feet, while dwarf varieties stay below 2 feet. Use this feature to select the right type for your space.
Flower Color and Shape
Delphinium flowers come in shades of blue, purple, pink, and white. Some hybrids display bi-color or variegated petals. The shape of the flowers can vary from the classic spiky form to more rounded or bell-shaped blooms.
