Coreopsis, also known as tickseed, is a cheerful and easy-to-grow perennial known for its daisy-like flowers that bloom throughout the summer.
Characteristics:
- Flowers: Coreopsis produces bright, daisy-like flowers in shades of yellow, orange, red, pink, and sometimes bi-colored varieties.
- Height: Depending on the species and cultivar, coreopsis can range from compact varieties around 1 foot (30 cm) tall to taller types reaching 3 feet (90 cm) or more.
- Foliage: The foliage is usually fine-textured and can be green or tinged with shades of bronze.
Growing Coreopsis:
- Soil and Location:
- Coreopsis thrives in well-draining soil and prefers full sun but can tolerate some partial shade, especially in hotter climates.
- Planting:
- Plant coreopsis from nursery-bought plants or seeds in early spring after the last frost date or in the fall for blooms the following year.
- When planting, space the plants according to the specific variety’s recommended spacing, usually around 12 to 18 inches (30 to 45 cm) apart.
- Watering:
- Water newly planted coreopsis regularly until they establish. Once established, they’re relatively drought-tolerant and require minimal watering.
- Temperature and Maintenance:
- Coreopsis is generally low-maintenance and thrives in moderate temperatures. Deadhead spent flowers to encourage continuous blooming.
- Some varieties may benefit from shearing after the first bloom to encourage new growth and additional flowering.
- Fertilization:
- Coreopsis doesn’t usually require heavy fertilization. Adding organic matter to the soil before planting can provide sufficient nutrients.
- Pest and Disease Control:
- Coreopsis is relatively resistant to pests and diseases. However, keep an eye out for aphids or powdery mildew, especially in humid conditions.
- Overwintering:
- Coreopsis is perennial and will come back year after year. In colder climates, mulching around the plants in winter can help protect the roots.
Coreopsis is an excellent choice for borders, rock gardens, or wildflower gardens due to its long-lasting, colorful blooms and low-maintenance nature. With proper care—ensuring well-draining soil, adequate water, sunlight, and occasional deadheading—you can enjoy the vibrant beauty of coreopsis in your garden throughout the growing season.
