Definition of Delphinium and Larkspur
Delphinium
Delphinium is a genus of about 300 species of flowering plants in the family Ranunculaceae. They are commonly known as larkspurs, due to their resemblance to the spur of a lark’s foot. Delphiniums are native to the Northern Hemisphere, and are widely grown as ornamental plants for their striking flowers.
Some key characteristics of Delphinium include:
- Large, showy flowers with five petal-like sepals that are often blue, but can also be white, pink, purple, or yellow
- Elongated, tubular nectar spurs that extend from the center of the flower
- Tall, erect stems with deeply-lobed leaves
- Perennial plants that can reach up to 6 feet in height
- Often grown as a cut flower for use in floral arrangements
Delphinium has a long history of cultivation, dating back to ancient Greek and Roman times. In medieval Europe, the plant was believed to have magical powers and was used in medicine, as well as in love potions and spells. In the language of flowers, Delphiniums are often associated with grace and dignity.
There are numerous cultivars and hybrids of Delphiniums, with a wide range of flower colors, sizes, and shapes. They are popular in cottage and formal gardens, and are often grown as a backdrop to other flowers or as a focal point in the garden. They require well-drained soil and full sun, and are often propagated by division or from seed. However, Delphiniums are toxic to humans and animals if ingested, and care should be taken when handling them.
Larkspur
Larkspur is a common name used to refer to the annual flowering plant Consolida ajacis or to the perennial flowering plants of the genus Delphinium. Although Larkspur plants are related to Delphiniums, they are a separate genus of plants in the family Ranunculaceae. Larkspur is native to western Eurasia and is widely cultivated as an ornamental plant.
Some key characteristics of Larkspur include:
- Showy, spurred flowers that come in shades of blue, purple, pink, white, and red
- Elongated racemes of flowers that can reach up to 4 feet in height
- Annual plants that can self-seed and naturalize in the garden
- Leaves that are deeply lobed and divided
- Commonly used in cut flower arrangements
Like Delphiniums, Larkspur has a long history of cultivation and use in gardens and floral arrangements. They are often grown as an annual plant and are easy to cultivate from seed. Larkspurs are commonly associated with the month of July and are said to symbolize love, affection, and a happy life. In some cultures, Larkspurs are also believed to have protective qualities and are used in herbal remedies to treat a range of ailments.
While Larkspurs are relatively easy to grow, they do require well-drained soil and plenty of sun. They can be susceptible to fungal diseases and pests, so proper care and maintenance is important to keep them healthy. Larkspurs are a popular choice for cutting gardens, and their showy flowers are often used in bouquets and arrangements.
