What is Larkspur?
Delphinium or Larkspur, known scientifically as Consolida, is a genus of about 40 annual flowering plants belonging to the buttercup family, Ranunculaceae. These delicate plants are known for their tall, spiky clusters of flowers that come in a range of vibrant colors. They add an elegant touch to any garden with their long stems and soft, feathery leaves.
Is Larkspur Poisonous?
Yes, Larkspur is highly poisonous to humans and animals if ingested. All parts of the plant contain toxic alkaloids that can cause severe gastrointestinal discomfort, respiratory problems, and even death. It is crucial to handle this plant with care and ensure that it is kept out of reach of children and pets.
Is Larkspur a Perennial?
Larkspur is generally considered an annual plant, completing its life cycle in one growing season. However, some species can behave like short-lived perennials in certain climates, particularly where the winters are mild.
What Color is Larkspur?
Larkspur flowers come in a variety of colors including blue, purple, pink, and white. The most common and popular color is a rich, vibrant blue, which makes a striking addition to any garden.
What Does a Larkspur Look Like?
Larkspur plants are characterized by their tall, slender stems that can reach up to four feet in height. The flowers are arranged in loose, branching spikes, each flower having five petal-like sepals and a spur that gives them their distinctive appearance. The leaves are finely divided and feathery, adding to the plant’s delicate charm.
When Does Larkspur Bloom?
Larkspur typically blooms in late spring to early summer, with flowers appearing from May to July. The exact blooming time can vary depending on the climate and growing conditions.
When to Plant Larkspur Seeds?
Larkspur seeds should be planted in the fall for the best results. They require a period of cold stratification, meaning they need exposure to cold temperatures before they will germinate. Planting the seeds in the fall allows them to undergo this natural process over the winter months.
Are Larkspur and Delphinium the Same?
Larkspur and Delphinium are often confused because they are both tall, spiky flowers in the Ranunculaceae family. However, they belong to different genera. Larkspur (Consolida) is an annual, while Delphinium is a perennial. Additionally, Delphinium flowers are typically larger and more densely packed on the spikes than Larkspur flowers.
How to Grow Larkspur?
Growing Larkspur is relatively easy if you follow a few simple guidelines. They prefer full sun to partial shade and well-draining soil. Sow the seeds directly into the garden in the fall, cover lightly with soil, and water gently. Once they germinate and establish, thin the seedlings to about 12 inches apart. Keep the soil consistently moist but not waterlogged.
How to Propagate Larkspur?
Larkspur is most commonly propagated by seed. Collect the seeds from mature plants in the late summer or fall. Store them in a cool, dry place until you’re ready to plant them in the fall. Direct sow the seeds into prepared garden beds and cover lightly with soil.
How Long Do Larkspur Seeds Take to Germinate?
Larkspur seeds generally take about 2 to 3 weeks to germinate, depending on the soil temperature and moisture levels. Cold stratification can help improve germination rates and ensure more uniform growth.
Do Deer Eat Larkspur?
No, deer typically avoid Larkspur due to its toxicity. This makes Larkspur a great choice for gardens in areas where deer are a problem, as it is unlikely to be eaten by them.
Can You Grow Larkspur in Pots?
Yes, you can grow Larkspur in pots. Choose a large, deep container with good drainage, and fill it with a well-draining potting mix. Sow the seeds in the fall, cover lightly with soil, and keep the soil moist. Place the pot in a sunny location and protect it from harsh winter conditions if necessary.
Larkspur vs Lupine
Larkspur and Lupine both have tall flower spikes, but they belong to different plant families. Lupine (Lupinus) is part of the legume family and has flowers that are arranged more tightly on the spike. Additionally, Lupine flowers have a unique pea-like shape, whereas Larkspur flowers are more open and delicate.
Larkspur vs Foxglove
Larkspur and Foxglove (Digitalis) both produce tall, spiky flower clusters, but they differ significantly. Foxglove flowers are tubular and arranged in a more orderly, dense spike, and the plants themselves are biennial or perennial. Larkspur, on the other hand, has more loosely arranged, spurred flowers and is typically an annual.
Larkspur vs Lavender
Larkspur and Lavender (Lavandula) are quite different in terms of appearance and growing requirements. Lavender is a perennial shrub with fragrant, grey-green foliage and spikes of purple flowers. Larkspur, as mentioned, is an annual with tall, slender spikes of flowers in various colors. Lavender prefers dry, well-draining soil and full sun, while Larkspur thrives in cooler, moist conditions.
Larkspur vs Snapdragon
Larkspur and Snapdragon (Antirrhinum) both produce colorful, spiky flowers, but their growth habits and flower structures are different. Snapdragon flowers are more tightly packed and have a distinct, mouth-like shape that gives them their name. Larkspur flowers are more open and delicate. Snapdragons are also typically more compact plants compared to the taller, slender Larkspur.
What to Plant with Larkspur?
Larkspur pairs beautifully with other cottage garden favorites like poppies, foxgloves, and snapdragons. Their tall, spiky form adds height and structure to mixed borders, and their variety of colors can complement a wide range of other flowers. Consider planting them with shorter, mounding plants to create a layered effect in your garden.
