types of delphinium

Delphinium is a perennial flowering plant in the buttercup family Ranunculaceae. They are mostly known for their showy flowers, which can be blue, white or pink. Delphiniums grow from an underground corm and have long stems with lanceolate leaves arranged alternately on either side of the stem. The name “delphinium” comes from the Latin word leporinus, which means “of a hare.” The common name delphinium also refers to other plants in genera of Lilaeopsis and Erodium that resemble true delphiniums, but belong to different botanical families.

FAQS:

What type of soil and light conditions do delphiniums need?

Delphiniums prefer well-drained, moist soil that is in partial shade to full sun.

How do you care for your delphiniums to ensure their best appearance possible?

Deadheading the flowers helps keep them looking good. It also helps prevent disease and pests from forming on the plant.

Additionally, if your delphiniums appear to be getting too leggy, you can cut them back to about six inches in height and then mulch them.

If the temp gets below 25F, you should also protect it by covering the plant so that all parts are covered. You may want to use a commercially available frost blanket to protect your plant.

Why did my delphinium bloom last year, but it is not blooming this year?

When growing these plants, you need to understand that the first year is spent getting the plant established. Therefore, the blooms are not common during this year.

They usually bloom in the second year onwards if they are healthy. To ensure that your delphiniums have a chance to become established and survive, you may want to think about planting them in pots or cell trays before moving them into the ground.

Conclusion:

Delphiniums are very beautiful plants that have many uses around the home, for example as an outdoor plant they make a wonderful addition to any garden. They are also used in many gardens as part of a design in conjunction with other plants such as roses and hydrangeas.
