Because of its refined form and vivid hues, the delphinium holds special meanings in different cultures.

In Asia, the plant was introduced under Western influence. In Japan, it is popular in Western-style gardens, where its cool blue shades are enjoyed as a refreshing feature of summer scenery.

Historical Episodes

The name “delphinium” originates from the Greek word delphis (dolphin), inspired by the resemblance of its buds to the shape of a dolphin.

In ancient Greece, the flower was offered to the gods and used in rituals and festivals.

In Europe, from the Middle Ages onward, delphiniums became a highlight of noble gardens. With the rise of British gardening culture in the 16th century, numerous varieties were developed. By the 19th century, breeding also flourished in France and Germany, earning the flower the title “aristocrat of the garden.”

In the United States, active hybridization in the early 20th century produced large, vividly colored blooms, which helped spread the flower’s popularity in home gardens.

Gardening Advice

To grow delphiniums successfully, careful management is required.

Sunlight

They prefer bright conditions but should be sheltered from harsh direct sunlight to maintain a cool environment.

Watering

Water generously when the soil surface is dry, using well-drained soil to avoid waterlogging.

Soil

Choose soil with good drainage and moderate water retention; adding compost or leaf mold works well.

Fertilizer

Apply liquid fertilizer every two weeks during the growing season. Fertilizers rich in phosphorus enhance blooming.

Support

As the stems grow tall, staking helps prevent them from falling.

Cold resistance

They are relatively hardy, but in cold regions, mulching around the roots provides protection in winter.

Conclusion

The delphinium, with its refined beauty and striking shades of blue, has long fascinated people.

It carries a history rooted in Greek mythology, was celebrated as a noble flower in European gardens, and remains beloved in England, the United States, and Japan.

Today, it continues to enchant gardeners and admirers alike as a timeless classic of the garden.
