Coreopsis, often referred to as “tickseed,” is a much-loved perennial cherished for its vibrant blooms and resilience. This article presents an in-depth exploration of coreopsis, its aesthetic qualities, origins, cultivation requirements, and propagation methods.
What is Coreopsis?
Coreopsis is a genus of flowering plants in the Asteraceae family. These plants are native primarily to North and South America, with several species indigenous to Africa and Hawaii. The word “Coreopsis” is derived from the Greek words “koris,” meaning bug, and “opsis,” meaning view, which is a nod to their seeds’ appearance that looks somewhat like ticks or small bugs.
There are over 80 species of Coreopsis, including annuals and perennials, with the perennial varieties being most common in cultivation. They’re widely recognized for their ornamental value and are often used in border plantings, containers, and wildflower meadows.
What Does Coreopsis Look Like?
Coreopsis plants are known for their bright, daisy-like flowers that bloom from early summer to fall. The flowers typically come in shades of yellow and gold, although there are also varieties with pink, red, or bicolor blooms. The plant’s height can range from 6 inches to 4 feet tall, depending on the species and variety. The foliage is generally delicate and fern-like, adding to its overall charm.
The height of a Coreopsis plant can vary greatly depending on the specific variety, but in general, they tend to range from 6 inches to 3 feet tall.
For instance, the popular Coreopsis grandiflora, often referred to as ‘large-flowered tickseed,’ typically grows to about 1 to 2 feet tall. Coreopsis verticillata, or ‘threadleaf tickseed,’ usually ranges from 1 to 3 feet in height.
Regardless of their size, all Coreopsis species are known for their vibrant, daisy-like flowers that bring a pop of color to any garden. As always, check the specific growing instructions for the variety you have to ensure it receives the appropriate care.
Why is coreopsis called Tickseed?
Coreopsis, also known as Tickseed, gets its common name from the appearance of its seeds. The seeds are small, dark, and shaped somewhat like ticks, which prompted the colloquial name “Tickseed”. This is purely a physical resemblance and has no relation to ticks in terms of the insect or any related diseases.
Where is Coreopsis Native and Is it Invasive?
Coreopsis is native to various regions in the Americas, ranging from the prairies of the midwestern United States to the plains of Mexico and Central and South America. Despite their widespread distribution, they are generally not considered invasive. They’re often praised for their ability to naturalize in a controlled manner, adding color and biodiversity to the landscape without overtaking other plant life.
How to Grow Coreopsis
Understanding how to grow Coreopsis, also known as Tickseed, is a wonderful addition to any gardener’s skillset. This vibrant, perennial plant brings an explosion of color to your garden, attracting beneficial pollinators like bees and butterflies. Growing this flower not only enhances your garden’s aesthetic appeal but also promotes biodiversity.
By learning to grow Coreopsis, you’re inviting a burst of sunshine into your garden that’ll last from late spring through fall, fostering an ecosystem rich in beauty and beneficial insects. Here’s how to do it:
- Sun and Soil Requirements: It thrives in full sun, although it can tolerate some afternoon shade in hot climates. They prefer well-draining soil and can tolerate poor, rocky, or sandy soils, making them a good option for challenging sites.
- Planting: Coreopsis can be planted from seeds, nursery plants, or divisions. Space plants or seeds 12 to 18 inches apart. If you’re planting from seed, do so in the early spring.
- Watering and Fertilizing: While this flower is drought-tolerant once established, it’s best to provide regular water while the plants are young or during prolonged dry spells. Overwatering or poorly drained soil can lead to root rot. A light application of a balanced slow-release fertilizer in the spring can support growth, but avoid over-fertilizing, as this can lead to leggy growth and fewer blooms.
- Maintenance: Deadhead spent blooms regularly to encourage repeat blooming. Some varieties may also benefit from being cut back by a third in midsummer to rejuvenate the plant and encourage a fall bloom.
How to Propagate
Coreopsis can be easily propagated by seed, cuttings, or division. To propagate by division, divide the plant in the spring or early fall. Separate the plant into smaller pieces, each with a section of roots, and replant immediately. For propagation from cuttings, take cuttings in spring or early summer and root them in a mixture of sand and peat moss.
In conclusion, Coreopsis is an enchanting addition to any garden with its vibrant, long-lasting blooms and minimal care requirements. Whether you’re a seasoned gardener or just starting, growing Coreopsis can bring a burst of color and joy to your green space.
