How to Grow and Care for Delphinium, the Birth Flower of July

By Jill Brooke

Delphiniums are not only the flower for July but represent cheerfulness and goodwill. In fact, delphiniums are believed to be able to express feelings of encouragement and joy when people see them.

These are one of the best go-to perennials that easily entertains in a garden and then can be a cutting flower for a vase. In fact, delphiniums have been a popular flower in cottage gardens around the world since the 1500s.

Plant them at the back of the garden because these showy colorful plants tower over other flowers and can grow up to six feet tall. (Though most are 3 feet).

Like many other flowers that bloom in a rainbow of colors, each hue conveys a different meaning. Pink can be fickleness, white represents a happy go lucky disposition while purple is the color linked to having an open heart and wanting to love.

In all its interpretations for those who explore the language of flowers, one trait prevails. The delphinium suggests strong bonds of love and affability.

Well, how can’t you feel that upon seeing this bouncy exuberant flower with its tall elegant stalks that fill up a vase impressively with little fuss. In a garden, it stands out among other shorter flowers.

Growing Delphiniums

1) Grow in well-drained soil with full sun but must be sheltered from strong winds. They don’t like hot dry weather and prefer coos moist summers. Sudden wind or rain will upset them and you will lose blooms. They are a bit finicky.

2) Plant in the spring. With over 300 species, some can be planted from seed others from bulbs. The bulb versions are easier. As the Farmer’s Almanac advises, just dig a hole twice the diameter of the plant’s container.

3) Since it’s an alkaline-loving perennial, put lime or wood ashes over it to blossom more. You need to add some organic compost material. Whatever your favorite. Could even be cow manure.

4) Thin shoots when 3 inches high and leave a minimum of 2 or 3 shoots on each plant. Also don’t forget to stake after it grows to 12 inches.

5) Feed every few weeks. Yellow foliage or stunted growth means it needs more fertilizer. So just remember, this is a plant that likes to eat.

Also when finished blooming, cut flower stalks to the ground. Then look forward to your flowers for next year.
