Description

Coreopsis rosea is a rhizomatous perennial that forms dense, bushy clumps. It grows up to 2 feet (60 cm) tall. Leaves are linear, grass-like, and light green. Flowers are daisy-like, up to 1 inch (2.5 cm) in diameter. They have pink untoothed rays and yellow center disks and appear singly on short stalks in mid-summer.

How to Grow and Care

Most varieties are easy to grow and are not particular about soil quality or pH. Many can be grown from seed, either started indoors, 4-6 weeks before your last expected frost, or direct-seeded outdoors. Many will seed themselves. However, the hybrid varieties do not grow true to seed.

Coreopsis will need regular water when first planted until they are established. After that, they are pretty drought tolerant.

Deadheading will keep the plants blooming throughout the summer. However, some of the smaller flowered varieties are difficult to deadhead, and you may prefer to shear the plants once the first flush of flowers fade. After that, they will fill in quickly.

Most Coreopsis plants will form tidy clumps, but some taller species may require staking to look attractive, especially if grown in partial shade.

Although they are rugged plants, they don't tend to live more than 3 to 5 years. Therefore, a decrease in flowering is a signal it is time to divide the plants or plant some new ones from seeds.
