Coreopsis tinctoria is an annual plant with smooth, stiff, branching stems. It grows up to 4 feet (1.2 m) tall and up to 18 inches (46 cm) wide. Leaves are glabrous, pinnately divided, tending to thin at the top of the plant, and up to 3 inches (7.5 cm) long. Flowers are brilliant yellow with maroon or brown centers of various sizes and up to 2 inches (5 cm) in diameter. Flowering typically occurs in mid-summer. The small, slender seeds germinate in fall or early spring.

How to Grow and Care

Most varieties are very easy to grow and are not particular about soil quality or soil 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. 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. They will fill in quickly.

Most Coreopsis plants will form tidy clumps, but some of the 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. A decrease in flowering is a signal it is time to divide the plants or plant some new ones from seeds. See more at How to Grow and Care for Coreopsis.
