Last Updated on August 9, 2022 by Real Men Sow

Coreopsis is a bright, cheerful perennial and annual that blooms in summer. They also have herbaceous perennials. Coreopsis, also known as tickseed, can either be an annual plant (lasting one year) or a perennial plant (lasting many years).

What colour is coreopsis plant

Perennial coreopsis bears mostly yellow flowers, with some bi-colored and pink-flowered varieties. An annual variety offers a wider range of flower colors, including red, pink, and yellow. Coreopsis daisies are beautiful and colorful. They are usually single but some may have doubles. Coreopsis

You can grow annual and perennial coreopsis from seeds easily. Perennial varieties can also produce flowers in their first year, if they are sown early. Coreopsis with taller stems that bear flowers make great cut flowers, however, they’re also a great plant for wildlife attraction. They attract butterflies, bees, and other pollinators. The seeds are eaten by birds.

How To Grow Coreopsis

Perennial coreopsis is a sturdy and reliable plant for summer color. These perennials are herbaceous and can be regrown each spring. Plant them in spring or autumn to establish them before the main season. However, they can also be established in summer provided they are watered well. Plants should be spaced between 40-50 cm depending on the variety.

Should you grow coreopsis plants in pots or outdoors?

Plant annual coreopsis outdoors where they will bloom or in pots that have cover to protect them from the elements. Plant tender coreopsis in containers and borders after the last frosts. Put them in light shade or sun, with well-drained soil. You can grow them in any type of fertile soil. However, it must be well-drained. Use peat-free, multi-purpose potting soil for pots.

Where To Grow Coreopsis

Coreopsis thrives in either full sun or partial shade. This perennial grows well when it is surrounded by other herbaceous plants and shrubs. Coreopsis is also an annual that creates dazzling summer colors in large pots and borders. While taller varieties can be grown in the ground, shorter bushy varieties work well in large pots and borders. Mixing tall coreopsis with other annual flowers creates brightly-colored mixed plants that add a jewel-like shine to an informal summer-flowering meadow.

How To Care For Coreopsis

Perennial varieties need little care once established. For taller varieties, support or staking may be necessary in windy areas. Before new spring leaves appear, it is important to remove all dead growth.

Protecting annual coreopsis plants in meadow or border mixtures may be necessary for their small size. Especially when plants are young, watering is a must during dry spells.

How often should you water coreopsis plant

Water them frequently if it is being grown in pots for summer display. You can feed your Coreopsis every two weeks starting in late summer with a liquid fertilizer rich in potash, such as tomato fertilizer.

Coreopsis plants in pots need to be deadheaded regularly to maintain their appearance and encourage more blooms. You can also deadhead perennials in borders, but leave the heads on for food for seed-eating birds such as finches.

How To Propagate Coreopsis

You can sow annual coreopsis seeds in the ground, where they will bloom. You can also plant seeds in pots and trays covered from late winter through spring. Sow the seed in moist soil. Cover it with no more than 0.5 cm of soil. Space your seedlings at 15 cm apart. Sow perennial coreopsis seeds undercover in the late winter to ensure germination. To plant the seeds in the ground, you can grow them in pots.


If you have perennial coreopsis older than a few years and have formed clumps of good size, they can be lifted and divided and planted in the spring. You can remove the basal shoots from perennial coreopsis by carefully removing a portion of the root. This is done in spring. Plant in small pots, and then you can plant them later in the year.

Issues when growing coreopsis plants

Coreopsis is a reliable and easy-to-grow plant that has rarely been damaged. Overfeeding plants in the borders can cause leafy growth to increase at the expense of flowers. Young plants, especially seedlings, may be attacked by slugs or snails.

Advice On Buying Coreopsis

  • You have many options to choose from, so you can find the right one for your garden.
  • Keep in mind that while specialist nurseries might have more options, large online retailers may have lower prices.
  • Only purchase the best plants. Before you plant, make sure to inspect the plant for any signs of damage or pests.
