Tips For Growing Coreopsis (Tickseed)
Coreopsis (Tickseed) are long-blooming native wildflowers that are easy-to-grow and provide ample nectar for butterflies. They’re resistant to browsing rabbits and deer. Coreopsis can be divided into two groups that have different growing requirements: Coreopsis grandiflora and Coreopsis verticiliata (Threadleaf Tickseed) cultivars and hybrids.
1. Coreopsis grandiflora types (Tickseed) – these cultivars are generally grown from seed and are a short-lived perennial (3 to 4 years).
Preferred growing conditions:
- Needs sandy/gravely and sandy loam type soils. Avoid clay.
- Does best with gravel mulches.
- After their second growing season, only requires deep but infrequent watering. Too much water makes them floppy and shortens their lifespan.
- Plant in full hot sun.
- Adding just a few handfuls of compost and Yum Yum Mix in the planting hole is enough. Don’t plant into a rich, highly-amended soil.
- Deadhead plants to prolong bloom. Leave a few seed pods on the plants to encourage re-seeding.
2. Coreopsis verticillata (Threadleaf tickseed) and hybrids – These are long-lived perennials that spread by rhizomes to form wide, dense growing clumps.
Preferred growing conditions:
- These species grow in a wide range of soil types including clay. Avoid very alkaline soils as they may get chlorotic (yellow foliage) due to unavailability of iron and other trace minerals.
- These plants don’t need mulching except in hot climates.
- These are moisture-loving perennials and do best in moderately moist soil conditions.
- Plant in full sun areas.
- They like compost-enriched soils at planting time.
Threadleaf tickseed plants are often late to wake in spring from dormancy, so don’t worry when other neighboring perennials wake up first.
Garden care for all types of Coreopsis:
- Fertilize Coreopsis just once in fall with Yum Yum Mix and Planters II. In addition, for C. verticillata types, green sand is recommended for alkaline soils to correct or prevent chlorosis.
- Plants can be divided in mid-spring when clumps die-out in the center or become too large for their place in the garden.
- Leave all Coreopsis varieties standing over the winter and cut back to 1-2″ inches above the soil in mid-spring when the plants begin to wake up.
Early Sunrise is a great border plant, adding doubled blooms on 2 ft. stems in midsummer. Glossy foliage and a neat habit make it a favorite.
North American Native Wildflowers: Our beautiful wild Coreopsis species, and how they’ve been improved. The Coreopsis group is one of the great gifts of North America to the plant world. Almost all the species of Coreopsis that the world now knows and loves are North American native wildflowers. The following ones are particularly famous, and all these are native over most of the eastern states.
Plains Coreopsis, C. tinctoria, also called Calliopsis, is a much-loved wild annual and is a mainstay of wildflower meadow seed mixtures. (See seed in our Wildflower Encyclopedia)
Lanceleaf Coreopsis, C. lanceolata is the famous perennial golden daisy that decorates fields over almost the whole east. (See seed in our Wildlfower Encyclopedia)
The Rosy Coreopsis, C. rosea is another wild perennial which is finer-leaved than Lanceleaf, and has been hybridized into some of the best new colors and forms.
Thread Leaf Coreopsis, C. verticillata is a small delicate-appearing perennial wildflower with fine leaves and stems. This one has been made into many popular garden hybrids, most famous being Moonbeam, a huge hit when it hit the gardening market.
Tickseed Coreopsis C. grandiflora is a common southern native and has golden flowers 1 to 2 1/2 inches across.
Since these wonderful plants are North American natives, their hybrids are right at home in your perennial gardens.

Coreopsis (Coreopsis Grandiflora Early Sunrise) – Start Coreopsis seeds in spring for blooms the first season! Early Sunrise is such an excellent performer that it won the AAS Gold Medal. It has a proven record of glorious blooms lasting for a long season. Readily grown from flower seed, this variety is a compact plant, reaching 18 – 24 inches tall and spreads to 18 inches wide. It is known for blooming earlier than other varieties of Coreopsis, and it has large 2 inch double golden yellow blooms. It makes an excellent cut flower, and butterflies will flock to it! Coreopsis Grandiflora sometimes is called Bigflower Coreopsis or Largeflowered Tickseed.
Coreopsis plants love the summer sun and heat. They are fairly drought tolerant once they are well-established. They are not too picky about soil, but it does need to drain well. Deadheading helps to encourage continuous blooms up until the first frost. Coreopsis care includes leaving new fall growth at the base of the Coreopsis plant for wintering over and dividing the plant every 2 – 3 years. Directly sow Coreopsis flower seed outdoors in spring into a prepared seed bed. Soil should be loosened and weed free. Press the Coreopsis seeds into the soil but do not cover them. Keep the seed moist until germination. It will bloom the first year after sowing flower seed.
Growing Coreopsis: How To Care For Coreopsis Flowers
Coreopsis spp. may be just what you need if you’re looking for lasting summer color after most perennial flowers fade from the garden. It is easy to learn how to care for coreopsis flowers, commonly called tickseed or pot of gold. When you’ve learned how to grow coreopsis, you’ll appreciate their sunny blooms throughout the gardening season.
Coreopsis flowers may be annual or perennial and come in a variety of heights. A member of the Asteraceae family, blooms of growing coreopsis are similar to those of the daisy. Colors of petals include red, pink, white and yellow, many with dark brown or maroon centers, which makes an interesting contrast to the petals.
Coreopsis is native to the United States and 33 species are known and listed by the Natural Resources Conservation Service of USDA on their website’s plant database. Coreopsis is the state wildflower of Florida, but many varieties are hardy up to USDA plant hardiness zone 4.
How to Grow Coreopsis Plants
It is equally easy to learn how to grow coreopsis. Simply seed a prepared area of un-amended soil in spring in a full sun location. Seeds of coreopsis plants need light to germinate, so cover lightly with soil or perlite or simply press seeds into moist soil. Keep the seeds of coreopsis plants watered until germination, usually within 21 days. Care of coreopsis may include misting the seeds for moisture. Sowing plants in succession will allow for an abundance of growing coreopsis.
Coreopsis plants may also be started from cuttings from spring to mid-summer.
Care of Coreopsis
Care of coreopsis is simple once flowers are established. Deadhead spent blooms on growing coreopsis often for the production of more flowers. Growing coreopsis may be cut back by one-third in late summer for a continued display of blooms.
As with many native plants, coreopsis care is limited to occasional watering during extreme drought, along with the deadheading and trimming described above.
Fertilization of growing coreopsis is not needed, and too much fertilizer may limit flower production.
Now that you know how to grow coreopsis and the ease of coreopsis care, add some to your garden beds. You’ll enjoy this reliable wildflower for long lasting beauty and the simplicity of how to care for coreopsis flowers.
Several coreopsis species are perennials popular in the garden, all of them sporting bright daisylike flowers on wiry stems. Height varies with species and cultivar, ranging between nine inches and three feet. These perennial flowers bloom in shades of yellow, orange, and pink, with lance-shaped, oval, or threadlike leaves.
How to grow: Coreopsis species are happy in almost any well-drained garden soil in full sun. They are drought-resistant and an outstanding choice for hot, difficult places. Deadheading and frequent division keep plants going strong.
Propagation: By division in spring or from seed.
Uses: Excellent for wild gardens, containers, and in garden beds, these flowers are also popular for cutting. The smaller types look great in hanging baskets and as edging plants.
Related species: Coreopsis grandiflora Sunray bears double golden-yellow flowers on two-foot stems. C. lanceolata Brown Eyes has big yellow daisies with brown splotches on plants over two feet tall. C. verticillata Moonbeam has primrose yellow daisies in low-growing carpet and is a landscaping favorite. C. rosea is similar in form to Moonbeam but has pink flowers. It is not as strong a grower.

Common Disease Problems
Aster Yellows: Plants are stunted, develop witch’s brooms (excessive growth), petals turn green and become deformed. This virus-like condition is spread by leafhoppers. Burpee Recommends: Remove infected plants and control leafhoppers. Remove weeds in the area which serve as alternate hosts to the disease.
Bacterial Leaf Spot: First signs are small translucent spots with a broad yellowish edge that slowly enlarge and become angular or irregularly circular with a reddish center. It thrives in cooler temperatures. The disease may also affect and disfigure flower heads.Burpee Recommends: Remove infected plants. Avoid overhead watering. Do not work around plants when they are wet.
Botrytis: This fungus causes a grey mold on flowers, leaves, stems and buds. It thrives in cool wet weather conditions. Burpee Recommends: Remove affected plant parts, avoid watering at night and getting water on the plant when watering. Make sure plants have good air circulation. Contact your Cooperative Extension Service for fungicide recommendations.
Downy Mildew: This fungus causes whitish gray patches on the undersides and eventually both sides of the leaves. Burpee Recommends: Avoid overhead watering. Provide adequate air circulation, do not overcrowd plants. Do not work around plants when they are wet.
Powdery Mildew: This fungus disease occurs on the top of the leaves in humid weather conditions. The leaves appear to have a whitish or greyish surface and may curl. Burpee Recommends: Avoid powdery mildew by providing good air circulation for the plants by good spacing and keeping weeds under control. Contact your Cooperative Extension Service for fungicide recommendations.
Common Pest and Cultural Problems
Aphids: Greenish, red, black or peach colored sucking insects can spread disease as they feed on the undersides of leaves. They leave a sticky residue on foliage that attracts ants. Burpee Recommends: Introduce or attract natural predators into your garden such as lady beetles and wasps which feed on aphids. You can also wash them off with a strong spray, or use an insecticidal soap.
Leafhoppers: Leafhoppers cause injury to leaves and stunt growth. They also spread disease. Burpee Recommends: Remove plant debris. Use insecticidal soaps. Consult your Cooperative Extension Service for other insecticide recommendations.
Slugs: These pests leave large holes in the foliage or eat leaves entirely. They leave a slime trail, feed at night and are mostly a problem in damp weather. Burpee Recommends: Hand pick, at night if possible. You can try attracting the slugs to traps either using cornmeal or beer. For a beer trap, dig a hole in the ground and place a large cup or bowl into the hole; use something that has steep sides so that the slugs can’t crawl back out when they’re finished. Fill the bowl about ¾ of the way full with beer, and let it sit overnight. In the morning, the bowl should be full of drowned slugs that can be dumped out for the birds to eat. For a cornmeal trap, put a tablespoon or two of cornmeal in a jar and put it on its side near the plants. Slugs are attracted to the scent but they cannot digest it and it will kill them. You can also try placing a barrier around your plants of diatomaceous earth or even coffee grounds. They cannot crawl over these.
Spider Mites: These tiny spider-like pests are about the size of a grain of pepper. They may be red, black, brown or yellow. They suck on the plant juices removing chlorophyll and injecting toxins which cause white dots on the foliage. There is often webbing visible on the plant. They cause the foliage to turn yellow and become dry and stippled. They multiply quickly and thrive in dry conditions. Burpee Recommends: Spider mites may be controlled with a forceful spray every other day. Try hot pepper wax or insecticidal soap. Check with your Cooperative Extension Service for miticide recommendations.
Thrips: Thrips are tiny needle-thin insects that are black or straw colored. They suck the juices of plants and attack flower petals, leaves and stems. The plant will have a stippling, discolored flecking or silvering of the leaf surface. Thrips can spread many diseases from plant to plant. Burpee Recommends: Many thrips may be repelled by sheets of aluminum foil spread between rows of plants. Remove weeds from the bed and remove debris from the bed after frost. Check with your Cooperative Extension Service for pest controls.
Belonging to the daisy (Asteraceae) family, the 80-odd species in this genus are profusely flowering compact plants that are highly valued for the summer colour they bring to the garden. Encompassing annuals, perennials, and a few shrubs, these plants occur naturally in the Americas, particularly in southern USA and Mexico, and may be sprawling and mounding or upright and shrubby, and they make ideal subjects for meadow gardens or herbaceous borders, and are also excellent for cut flowers. Both the common name tickseed, and the genus name, which comes from the Greek word coreopsis, meaning bug-like, refers to the small black seeds that adhere to clothing and resemble ticks.
These mostly shrubby plants tend to have fairly simple, often shallowly lobed or linear leaves. The flowers are borne in abundance, and most often occur in golden yellow tones, though the numerous garden forms come in myriad shades. The tips of the ray florets are often toothed as if cut with pinking shears. The main flowering time is summer to autumn.
Coreopsis species are quite drought tolerant and are very easily cultivated in any bright sunny position with light well-drained soil. They will flower better with summer moisture, and over a longer period if they are deadheaded frequently. Some species are regarded as weeds in various parts of the world. All may be raised from seed, and the perennials will also grow from divisions or small basal cuttings of non-flowering stems.
