Delphinium, also commonly known as larkspur, is an exquisite and vibrant plant that adds a touch of elegance to any garden or landscape. Many people wonder if larkspur and delphinium are the same, and the answer is both yes and no. Let me explain further.
Larkspur and delphinium are often used interchangeably, but there are some subtle differences between the two. Larkspur is the common name for annual species of the Delphinium genus, while delphinium is the name given to the perennial species. In simpler terms, all delphiniums are larkspurs, but not all larkspurs are delphiniums.
The confusion arises from the fact that both larkspur and delphinium belong to the same botanical family, Ranunculaceae, which also includes other beautiful flowers like clematis, columbines, and poppies. However, the main distinction lies in their growth habit and lifespan.
Larkspur is typically an annual plant, meaning it completes its life cycle within a single growing season. These plants sprout from seeds, grow and bloom, produce seeds, and then die off, all within a year. On the other hand, delphiniums are perennials, which means they have a longer lifespan and can come back year after year. Perennial delphiniums have a woody stem base and can live for several years if properly cared for.
In terms of appearance, both larkspur and delphiniums exhibit tall, spiky flower stalks adorned with numerous colorful flowers. Their blooms come in a wide range of colors, including shades of blue, purple, pink, white, and even yellow. These flowers have a distinct shape, with a spurred petal at the back, which gives them their common name – larkspur, as the shape resembles a lark’s spur or claw.
Larkspur and delphiniums are beloved by gardeners and floral enthusiasts alike for their stunning beauty and ability to attract pollinators like bees and butterflies. They are often used in cut flower arrangements due to their striking appearance and long-lasting blooms.
Caring for larkspur and delphinium is relatively similar, regardless of their annual or perennial nature. They thrive in full sun or partial shade and prefer well-drained soil that is rich in organic matter. Regular watering is necessary to keep the soil consistently moist, especially during periods of drought.
When it comes to propagation, larkspur and perennial delphiniums can both be grown from seeds. However, perennial delphiniums can also be propagated through division, where the plant is carefully separated into smaller sections and replanted. This can help rejuvenate an older plant and promote healthier growth.
While larkspur and delphinium are often used interchangeably, larkspur refers specifically to the annual species within the Delphinium genus, while delphinium encompasses the perennial species. Both plants share similar characteristics in terms of appearance and care, making them a delightful addition to any garden or landscape.
