The name “delphinium” comes from the Greek word delphis (dolphin), referring to the resemblance of its flower buds to the shape of a dolphin. In ancient Greece, delphinium was associated with the gods and used in religious ceremonies and festivals.

During the medieval period in Europe, delphinium became a popular ornamental plant in noble gardens.

In the 19th century, France and Germany contributed to its further refinement, solidifying its status as a garden classic.

In the United States, delphinium breeding gained momentum in the early 20th century, leading to the development of large-flowered, vibrant varieties. These improvements made the plant more accessible to home gardeners, contributing to its widespread popularity.

Gardening Advice

Proper care is essential to maintain the health and beauty of delphiniums. Follow these guidelines for successful cultivation:

Sunlight

Prefers full sun but benefits from some shade in extremely hot climates.

Watering

Water thoroughly when the soil surface is dry. Ensure good drainage to prevent root rot.

Soil

Use well-draining soil with good moisture retention. Adding compost or organic matter improves soil quality.

Fertilization

Apply a liquid fertilizer every two weeks during the growing season. Phosphorus-rich fertilizers promote better flowering.

Support

Tall stems require staking to prevent bending or breaking.

Cold Resistance

While relatively hardy, mulching around the base in colder climates helps protect the roots during winter.
