30 Popular Types Of Delphinium Pictorial Guide

Delphinium is a stunning flowering plant that belongs to the buttercup family, Ranunculaceae. The genus Delphinium comprises around 250 species of annuals, biennials, and perennials that are native to the Northern Hemisphere, with the majority found in the mountainous regions of the Northern Hemisphere. These plants are commonly known as larkspurs, and they are widely grown for their beautiful flowers.

Larkspurs are tall, elegant plants that can grow up to six feet in height. The flowers are typically blue or purple, but they can also be pink, white, or yellow, depending on the species. The blooms are arranged in elongated spikes, and each flower has a distinctive spur that gives the plant its name. The foliage is deeply cut, and the leaves are arranged in a rosette at the base of the plant.

Delphiniums are popular garden plants, and they are widely grown for their showy flowers. They are typically grown as perennials, and they are often used to add height to a garden bed or border. They are also commonly used in cut flower arrangements and can add a pop of color to any floral display.

To grow delphiniums successfully, they need a fertile, well-drained soil that is enriched with organic matter. They prefer a slightly acidic soil with a pH range of 6.0 to 7.0. These plants require full sun to thrive, and they need to be watered regularly to prevent the soil from drying out. Larkspurs also benefit from the addition of a balanced fertilizer during the growing season.

Delphiniums are relatively easy to propagate, and they can be grown from seed or cuttings. Seed should be sown in the spring, and cuttings can be taken from the base of the plant in the autumn. The seedlings or cuttings should be transplanted into their permanent location in the garden once they have become established.

One of the challenges of growing delphiniums is controlling pests and diseases. These plants are susceptible to a range of pests, including aphids, slugs, and snails. They are also prone to fungal diseases, such as powdery mildew and botrytis blight. To prevent these issues, it’s important to keep the plants healthy by providing them with the proper growing conditions and by practicing good garden hygiene.

In conclusion, delphiniums are a beautiful and popular garden plant that add color and height to any garden bed or border.

How To Grow And Care For Delphinium

Delphiniums are tall, stunning perennial plants with vibrant, showy blooms that are perfect for adding color and interest to any garden or landscape. Here are some tips on how to grow and care for delphiniums:

• Location: Delphiniums prefer a sunny location with well-drained soil. Ensure that there are at least six hours of direct sunlight each day in the area.

• Soil: Delphiniums prefer a slightly acidic soil with a pH of around 6.5. They require soil that is moist but well-drained, so ensure that the soil does not become waterlogged.

• Planting: Plant delphiniums in the spring, after the last frost. Dig a hole that is twice as wide as the plant’s root ball, and plant it at the same depth it was growing in its pot. Space plants about two feet apart.

• Watering: Delphiniums require consistent moisture, especially during the hot summer months. Depending on the weather, water the plants deeply once or twice per week.

• Fertilizing: Delphiniums benefit from slow-release fertilizer applied in the early spring before new growth appears. You can also use a liquid fertilizer every two weeks during the growing season to promote healthy growth and blooming.

• Support: Delphiniums can grow quite tall, so it’s essential to provide support for them. Use stakes or a trellis to keep the plants upright, especially during windy weather.

• Pruning: After the initial blooming period, cut back the plant’s spent flower stalks to encourage the development of new blooms. In the fall, after the plant has died back, cut it back to about 3 inches above the ground.

By following these tips, you can grow healthy, beautiful delphiniums that will add color and interest to your garden for years to come.

How To Propagate Delphinium

Delphiniums can be propagated by various methods, including seed propagation, division, and stem cuttings. Here are the steps for each method:

Seed Propagation:

• Collect delphinium seeds from the mature plant when the seed pods turn brown and start to open.
• Sow the seeds in a tray filled with potting soil or seed-starting mix and cover them with a thin layer of soil.
• Water the seeds gently and place the tray in a warm, well-lit area.
• Keep the soil moist and wait for the seeds to germinate, which usually takes around 2–3 weeks.
• Once the seedlings have developed two or three true leaves, transplant them into individual pots or directly into the garden.

Division:

• Dig up a mature delphinium plant in early spring or fall, when the plant is dormant.
• Gently separate the root ball into smaller sections using a sharp knife or garden spade.
• Replant the divisions immediately in well-draining soil, and water them well.

Stem Cuttings:

• Take a stem cutting from a healthy delphinium plant in the summer when the plant is actively growing.
• Cut a 3- to 4-inch section of stem just below a leaf node, and remove the leaves from the lower part of the stem.
• Dip the cut end of the stem in rooting hormone powder and plant it in a pot filled with moist potting soil or a mix of sand and peat moss.
• To create a humid climate, place a plastic bag or dome over the pot..
• Place the pot in a bright, but indirect, location and keep the soil moist.
• To create a humid climate, place a plastic bag or dome over the pot.

Layering:

• Choose a healthy delphinium plant and select a healthy stem that is low on the plant and long enough to reach the ground.
• Remove the leaves from the bottom of the stem, leaving a few leaves at the top.
• Make a small wound or nick on the stem where it touches the ground.
• Bury the wounded area of the stem in a shallow trench and secure it in place with a U-shaped wire or a small rock.
• Cover the stem with soil, leaving the top leaves exposed.
• Wait for the new roots to form while keeping the soil moist. This procedure often takes a few weeks to a few months.
• Once the new roots have formed, sever the layered stem from the parent plant and transplant it in a new location.

Grafting:

• Choose a healthy delphinium plant as the rootstock and a desirable variety as the scion.
• Cut a section of stem from the rootstock plant and make a diagonal cut across the stem.
• Cut the scion stem into a wedge shape that fits snugly into the rootstock stem.
• Insert the scion into the rootstock stem, and bind the two stems together with grafting tape or twine.
• Cover the graft with grafting wax or paraffin to prevent it from drying out.
• Place the grafted plant in a warm, well-lit area, and keep the soil moist.
• Once the graft has taken, the scion will start to grow, and the plant can be transplanted into a new location.

Propagation can be a rewarding way to increase your delphinium collection or share your plants with friends and family.
