How To Handle A Plant Called Larkspur?

Larkspur plants, also known as Delphinium and Consolida ajacis, are a classic cottage garden staple that produces tall, inexpensive, and fantastic cut flowers. They are easy to start from seed and prefer full sun, moist but well-draining soil, moderate watering, and cooler temperatures. Larkspurs are hardy plants that don’t need heavy staking from the ground, making them suitable for a wide range of zones.

There are two primary methods for introducing larkspur into your garden: direct seeding and transplanting seedlings. Direct seeding is the most common method, as it requires sowing seeds directly outdoors in most regions. Larkspurs prefer moderately rich, loose, well-draining soil, and they can handle a small amount of shade, but they are likely to flop and require stakes.

Larkspur plants require at least 6 hours of direct sun a day for the best blooms. Delphinium plants require full sun to part shade, and they prefer well-draining soil rich in organic matter. Delphinium plants can tolerate some shade, but too much can result in weak and spindly plants. Larkspur plants prefer consistently moist but not wet soil, as hot, dry conditions stunt their growth and inhibit blooming.

In summary, Larkspur plants are easy to grow and care for, with a preference for full sun, moist but well-draining soil, moderate watering, and cooler temperatures. They are also tolerant of some shade, but too much can lead to weak and spindly plants.

What is the vase life of larkspur?

Larkspur is a highly sensitive ethylene-sensitive flower with a vase life of 5 to 7 days. It is easy to grow and adds colorful spikes to spring gardens. The mix includes ‘Giant Imperial White King’, ‘Giant Imperial Blue Bell’, ‘Giant Imperial Blue Spire’, and ‘Frosted Skies’. The flowers are cold-tolerant and early to bloom, making them perfect for mixed bouquets. However, they are poisonous, including seeds, so caution is advised around children and pets. The flowers can be dried for later use.

Do larkspurs need deadheading?

Larkspur plants require two types of pruning: deadheading and end-of-the-season cutting back. Deadheading encourages longer blooming and maintains the plant’s compact appearance. End-of-the-season cutting back helps control diseases and pests, and prepares the plant for the new season. To prolong blooming, cut back flowers before they ripen, cutting the stem back to the main stem or visible buds. This keeps the plant tidy and compact.

Is larkspur poisonous to touch?

The larkspur plant is poisonous, with its leaves and seeds causing skin irritation and eating causing severe illness and death. Cattle are most likely to experience larkspur poisoning due to its early blossoming and lack of other grazing options. Larkspur toxicity is highest during early growth stages but remains toxic throughout its lifespan. Sheep and goats are not affected by larkspur and can graze away it in fields and ranges.

Is touching larkspur bad?

The larkspur plant is poisonous, with its leaves and seeds causing skin irritation and severe illness and death. Cattle are most likely to experience larkspur poisoning due to their early blossoming. Larkspur toxicity is highest during growth but remains toxic throughout their lifespan. Sheep and goats are not affected by larkspur and can graze away in fields and ranges. Human poisoning from eating the plant is rare, but skin symptoms from touching the leaves or seeds may include:

Do larkspur multiply?

Delphiniums are short-lived perennial plants that last between two to three years. However, they can multiply under proper conditions. They come in various varieties and can grow from tiny spikes to six-foot giants. To care for them, transplants should be planted in spring, with full or partial sun and moist but well-draining soil. They are heavy feeders and require weekly fertilization. Once flowering, remove flower stalks and mulch the plant in the fall.

Larkspurs prefer sunny spots but cool temperatures, so consider the planting location in relation to your growing zone. The plant can be left in the ground over winter but should be mulched in the fall.

Should you pinch out larkspur?

Pinching or cutting flowers can yield numerous blooms, but it’s important to know which flowers don’t like this treatment. Some flowers, like campanula, cockscomb, delphinium, dill, stock, larkspur, and most sunflowers, don’t like pinching. However, pinching can encourage bushing and spreading, resulting in more flowers and color. Pinching should be done at a node, depending on the plant’s compactness. Sweet peas can branch into a fuller plant with pinching.

Once satisfied with the plant’s shape, stop pinching and let it grow. Zinnias and cosmos are particularly generous bloomers if pinched. Pinching early promotes branching, then “pinch” by cutting flowers. Frequently picking bouquets can result in more flowers for your tables and friends.

How do you take care of a cut larkspur?

To ensure optimal freshness, it is recommended that stems be placed in cool water following the harvest. Larkspur flowers have a vase life of approximately five to seven days. The use of a floral preservative can extend this period. They are particularly susceptible to ethylene gas.

What kills larkspur?

Tordon® and Escort® were employed for the eradication of other broad-leaf forbs and larkspur.

What are the side effects of larkspur?

Larkspur, a plant native to the Mediterranean, is generally not toxic to horses unless there is a lack of suitable forage. However, its toxicity may vary depending on seasonal changes and field conditions. As the plant matures, it becomes less toxic. The alkaloids in the plant cause neuromuscular paralysis, with symptoms including constipation, colic, increased salivation, muscle tremors, stiffness, weakness, recumbency, and convulsions. Cardiac failure may occur and respiratory paralysis can lead to death.

Is larkspur cut and come again?

Larkspur is a one-cut crop, meaning that it produces multiple stems, allowing for harvesting over a period of approximately two weeks. To extend the harvesting period, it is recommended to sow the crop in two-week intervals. Larkspur can be planted as close as 4 inches apart, though spacing of 9 inches or closer is not recommended. The most prevalent spacing for these crops is 7 inches by 7 inches. To extend the harvesting period, it is recommended to sow the crop in two-week intervals.

How long do larkspur last?

Larkspur flowers typically bloom in the early fall, continuing to do so until the first frost, at which point they lose color and enter a dormant phase until the return of warmer weather. Upon the return of favorable temperatures, the plants emerge from their dormant state and continue to grow until the first frost.
