Delphinium aka Larkspur

Taxonomy

Delphinium is a genus of flowering plants in the family Ranunculaceae, consisting of about 300 species native to the Northern Hemisphere and tropical African mountains. The name Delphinium is derived from the Greek word δελφίνιον, meaning "dolphin," due to the shape of its flowers. However, all members of the genus are toxic to humans and livestock. The common name "larkspur" is shared between perennial Delphinium species and annual species of the genus Consolida. Consolida differs from other Delphinium species in its flower structure, with only one united petal, and in the fruit, which is a single follicle. It is a popular garden plant and cut flower, grown from seed every year in shades of pink, blue, purple, and white. Delphinium ambiguum is a rare houseplant that requires regular watering and well-draining soil to thrive. It prefers long-lasting, direct light and should be less than 1 foot from a window. If repotted each time it doubles in size, it should not need added fertilizers.

How to care for Larkspur

Difficulty

Larkspur requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

Water

Larkspur should be watered regularly, allowing the soil to dry out between waterings.

Soil

Larkspur loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Larkspur requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Larkspur will be sure to bring you many years of beauty and enjoyment.

Dormancy

During the cold period, it is common for Larkspur to go dormant and their growth may slow down, so waterings should be spaced out more during this period.

Toxicity

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

Fertilizer

The Larkspur should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.
