Coreopsis plants (also known as Tickseed) are deer resistant and attract butterflies. Our native Coreopsis are known for their beautiful yellow flowers and are prized for their long bloom time. Tickseed blooms from late spring to late summer, and the yellow blossoms are always welcome. Coreopsis flowers are easy to grow and make excellent cut flowers. These perennials prefer full sun and well-drained soil. Keep the plants deadheaded for the finest flowering results. Leave a few seed heads on the plant at the end of the season so it can self-seed.
Is tickseed a perennial or an annual?
Coreopsis are low-maintenance perennials with daisy-like flowers that thrive in the sun. They can withstand dryness, bloom for a long time, and thrive on poor, sandy, or rocky soil. Because of the odd shape of their seed capsules, Coreopsis is usually referred to as tickseed.
Is tickseed an invasive plant?
The National Garden Bureau, a non-profit organization dedicated to promoting the joys of home gardening, chooses one perennial, one annual, one bulb, and one edible plant to honor each year. It’s an excellent method to learn about a new plant or to learn more about one you already have.
The perennial coreopsis, sometimes known as tickseed, is the first of 2018’s four plants (Coreopsis). See 2018: Year of the Calibrachoa and 2018: Year of the Beet for details on two more 2018 winners.
Coreopsis is a genus of over 80 species that originated in the New World, with roughly 45 of them found in North America. Annuals and perennials, they are herbaceous plants that are generally small (rarely more than 2 1/2 feet/75 cm tall).
They have daisylike inflorescences that look like individual blooms but are actually compound flowers, as is typical of the Asteraceae family (sunflower family). They have a central disc of fertile florets surrounded by eight ray flowers (more in double and semi-double variations) and a serrated tip. The dominant flower color is yellow, with a reddish-brown halo on occasion.
The common name, tickseed, is derived from the Greek word coreopsis, which means “like a bug.” It gets its name from the bug-like appearance of the seeds of some former species, such as beggar-ticks, which have two projections that adhere to fur and clothing like ticks. Surprisingly, beggar ticks were long ago relegated to the genus Bidens. There are no “bug-like” seeds in any extant Coreopsis species!
Only a few species are cultivated, especially among the hardiest (the vast majority of species are tropical and cannot be grown in cooler climes except as annuals), but they nonetheless provide a wide range of options for our flower beds. Many coreopsis flowers continue to bloom throughout the summer, especially if deadheaded. Coreopsis has long been a favorite in gardens due to their prolific and long-lasting blooms… they also make great cut flowers.
Coreopsis are often meadow plants that thrive in full sun. They can take moderate shade, but prefer to be in direct sunlight. They adapt to all types of well-drained soils, and the most are drought-tolerant. Many species, however, rely on good drainage, particularly during the winter months. Clay soils are particularly troublesome. Many coreopsis thrive in raised beds because they provide improved drainage. Also, coreopsis prefers a soil that is not extremely fertile, as overly fertile soil can lead to weak stems that flop.
Pollinating insects (bees, butterflies, hoverflies, and others) enjoy coreopsis, and seed-eating birds frequent them in the fall and winter… if you don’t deadhead, of course!
From spreading beneath roots, rhizomatous types create masses of single stems. They’re the most hardy coreopsis, living for decades with little attention and being the most resistant to cold damp. They’re not usually invasive, but they may spread beyond their planting area if there are no plants to shade them out, necessitating control in some cases.
Clump-forming types have many stems that grow in tufts. They are usually short-lived in the garden, especially in soils that remain moist in the winter, frequently only surviving two or three years. You may, however, keep them alive for decades by creating new plants every two years from divisions or cuttings. As though to make up for their short lifespan, they are relatively simple to grow from seed, and many will bloom the first year from seed placed inside, which is a feat few perennials can achieve.
Annual variety, by definition, only live for one year. The majority of them survive by profuse self-sowing.
This coreopsis native to the southeastern United States stands out in a genus dominated by plants with narrow leaves by having trifoliate leaves that are relatively large, sometimes nearly spherical. The botanical (auriculata) and common names are derived from the two little leaflets at the base of the much larger center leaflet, which are supposed to resemble mouse ears.
The plant grows in a low rosette with little yellow flowers and evergreen leaves. It’s a long-lasting plant with short rhizomes that isn’t particularly invasive. It’s the first of the coreopsis to bloom, blossoming from spring to early summer because it’s a short-day plant (most others are long-day plants, with mid- to late-summer flowers).
The most popular mouse-ear coreopsis cultivar is ‘Nana,’ which grows to barely 10 in (25 cm) tall, but ‘Zamphir,’ which grows to 12-24 in × 12 in (30-60 cm x 30 cm) and has tubular ray blooms that resemble trumpets, is also extensively grown.
This coreopsis was once the most widely grown species in the genus (now C. verticillata), and most people just refer to it as coreopsis.
It’s a clump-forming plant that produces a plethora of green stems with narrow leaves. Lower leaves are simple, but those on flower stems have three to five lobes. The inflorescences are yellow orange in color, with a hint of reddish-brown at the base of the deeply serrated ray flowers. They range in size from 1 in to 2 in (2.5 cm to 6 cm) in diameter. It blooms all summer and into the fall, especially if you deadhead it (remove the faded flowers).
This species is one of the shortest-lived, very susceptible to powdery mildew and intolerant of damp winter conditions. Continue cuttings and divisions to keep it going. It also grows swiftly and easily from seed, blossoming the first summer after being grown from seed inside in March.
Large-flowered coreopsis can grow up to 36 inches (90 cm) in height in the wild, although practically all cultivated cultivars are much shorter, ranging from 16 inches to 24 inches (40 cm to 60 cm). The species and cultivars combine to form a cluster with a diameter of 12 in (30 cm). It’s a hardy plant that thrives in USDA and AgCan zones 3 and up.
Many hybrids are easy to grow from seed, including ‘Early Sunrise’ (double yellow, 16 in × 12 in/40 cm x 30 cm), which won an All-America Selections Award and a Fleuroselect Gold Medal in 1989.
How does tickseed spread?
Coreopsis has only one flaw: it is short-lived and unreliable in terms of perenniality. Many gardeners lament the fact that it only lasts two or three years. Others have seen that some varieties self-seed all over the garden and grow up in unexpected locations. Despite these drawbacks, this perennial favorite remains popular and is regularly planted or replanted year after year.
In order to improve Coreopsis, famous plantsman Darryl Probst and others instituted a number of hybridization programs.
Plant trials, including a three-year trial undertaken at the Mt. Cuba Center botanical garden in Delaware between 2012 and 2014, show that these hybridization efforts have improved the species.
With so many highly hybridized selections on the market these days, it’s a good idea to take a step back and learn about Coreopsis kinds and species.
Coreopsis is a genus of roughly 100 annual and perennial plants belonging to the Asteraceae (aster or daisy) family.
They can either form clumps or spread by rhizomatous roots.
The majority of Coreopsis species are clump forming.
Unfortunately, these are usually short-lived, and several of the members of this group are best handled as annuals.
Rhizomatous species have a longer lifespan and are more dependable perennials.
The following are some of the clump-forming and rhizomatous Coreopsis species commonly found at garden centers around the Mid-Atlantic:
- Coreopsis auriculata (Lobed or Mouse-Eared Coreopsis) Coreopsis auriculata (Lobed or Mouse-Eared Coreopsis) Orange-yellow blooms and oval-shaped leaves characterize this rhizomatous species. When in bloom, it develops spreading clumps that grow 2 to 3 feet tall and spreads quickly by rhizomes and seeds. A dwarf cultivar, ‘Nana,’ is half the size and one among the best in the genus. ‘Jethro Tull’ and ‘Zamphir,’ two popular C. auriculata cultivars, with open-ended, fluted ray blooms.
- C. grandiflora (Large-flowered Coreopsis) This clump-forming plant blooms early in the season and then blooms again later in the season.
- Although it is not a true perennial, lasting only 2 or 3 years on average, it has a strong ability to self-seed and may appear as a pleasant surprise throughout your garden.

Why is it called tickseed?
When rookie gardeners hear the word tickseed, they are likely to flee for their lives. Ticks are one of the parasites you don’t want to see in your yard or around your house, so the idea of a flower that can attract ticks sounds like a nightmare. Of course, anyone who knows anything about tickseeds knows that the name of this bloom isn’t a danger. (However, if ticks are a concern, try planting some of these deer-resistant plants!)
Tickseed is a popular name for Coreopsis and a few other genera of flowering plants with beautiful heads. Coreopsis, the genus name, means “bug-like” in Greek. The popular name Tickseed comes from the form and color of the seeds, which resemble ticks. Coreopsis are stunning blooms that would be a welcome addition to any garden. Tickseed comes in a variety of colors, including yellow, peach, red, and fuchsia, and they look great in patio planters and borders. Oh, and some of them also attract bees and butterflies, so you can be assured that your buds will be fertilized properly!
Is Black Eyed Susan deer resistant?
It may sound like a fantasy to have a lovely garden that returns year after year and keeps hungry deer away, but it is possible! Make a whole deer-resistant garden out of plants that these animals despise.
A hungry deer, of course, will eat just about anything. Because they are aromatic, thorny, or sap-filled, these plants repel. Use them in your garden to keep deer away from your favorite plants, such as garden phlox and hosta.
Bee balm’s minty aroma repels deer, yet pollinators can’t get enough of it. From July through August, Bee Balm blooms in violet blue, red, pink, or white and grows to be around 2-3 feet tall. For huge, robust blossoms, feed your Bee Balm with Espoma’s Organic Flower-tone fertilizer. Zones 48 are the best.
Lavender is a must-have for any garden since it repels pests and deer. Deer are put off by its fluffy and aromatic leaves. Between June and August, the majority of types bloom. Lavender requires full sun and well-drained soil to thrive. Throughout the growing season, feed with Espoma’s Plant-tone. Zones 59 are suitable for this plant.
Black-eyed susans thrive in the sun, their dark brown centers poking out from among the gold or golden petals. Deer and bunnies keep away from it because it is coated with coarse hair. These daisy-like blossoms are ideal for a bouquet in the late summer or fall. They reach a height of around 2 feet and can withstand extreme heat and drought. In zones 39, grow in full sun.
Deer despise yarrow, a bright yellow perennial with fluffy foliage. It blooms for a long period of time, from June to September. It’s a tall bloom, growing to a height of 2.5-3 feet on average. With Espoma’s Organic Garden Soil, you can give your flowers a firm soil foundation to help them bloom. Zones 38 are the best for this plant.
Deer-resistant gardens will benefit from the brilliant bell-shaped blossom with freckles on the interior. Because it is poisonous to deer, this plant is labeled as deer-resistant (and humans). Because many foxgloves are biennials, blossoms don’t appear until the second year after they’ve been planted. However, newer hybrid forms are perpetual. Because they are self-sowers, they will bloom year after year if the stalks are left in place. Keep the flowers going with Espoma’s liquid Bloom! Zones 49 are ideal for growing this plant.
Bleeding heart is a traditional cottage staple with a sap that deer dislike. Beautiful blooms emerge in late spring and linger throughout the summer, while the foliage remains attractive far into the fall. It’s easy to understand why their floral pendants, which come in rose pink and white hues, will be a success. It’s impossible to go wrong with a little romance. Zones 48 are suitable for this plant.
Is tickseed a wildflower?

The official wildflower of Florida is Coreopsis, popularly known as tickseed, and includes all 12 species native to the state. Many of these are unique to North Florida and the Florida Panhandle. Leavenworth’s tickseed (Coreopsis leavenworthii), the most abundant species, is almost totally indigenous to Florida, with the exception of two Alabama counties. Leavenworth’s tickseed blooms all year. Its natural habitat is mesic pine flatwoods, but it’s frequently employed in mixed wildflower and butterfly gardens, as well as sunny roadsides, highway medians, and powerline easements. It attracts a lot of pollinators and rabbits eat it (if you’re lucky enough to have them in your yard).
The daisy-like flowers are 1 to 2 inches diameter and feature a dark brown to black disk floret center surrounded by bright yellow scalloped ray florets. It has thin, narrow, bright green leaves that range from simple to lobed to deeply divided, giving the plant a more open appearance. The leaves are arranged in an oblique pattern. The stems are thin, glabrous, and have numerous branches. Awned achenes with membranous wings give birth to seeds. The common name “tickseed” comes from the plant’s similarity to little bugs.
Visit www.florida.plantatlas.usf.edu to see where wild populations of Leavenworth’s tickseed have been vouchered.
Gardening advice: Leavenworth’s tickseed requires a place that allows it to reseed. If other plants, such as wildflowers, are not too competitive, it can reseed between them. It can withstand some drought and drier soils, but it will not thrive. Reseeding is also possible on moist soils, which is vital for the species’ survival. The plants will produce another flush of blooms if they are cut down around the end of their bloom. They can also be mowed or string-trimmed to 68 inches.
Where is tickseed native to?
Golden tickseed is a tough, upright annual native to the southern United States that has spread across much of North America. The leaves are finely split and usually found on the lowest half of the plant. Bright yellow blooms with red centers bloom profusely on this prolific bloomer. Golden tickseed grows best in full light and in a variety of soil types. It’s a great plant for locations with poor drainage or that stay wet for a long time.
These airy plants, with their gleaming green stems and ball-shaped brown buds, are one of the principal color producers in any meadow in any location. The bi-colored golden blooms with mahogany centers are literally bursting at the seams “To have a long flowering season, “light up” a meadow. They’re also excellent at cutting. This is a plains species, but it is widely distributed. It’s known as “In the South, it’s known as “calliopsis,” and it’s popular all the way down to Florida. The coreopsis was just named Florida’s official state wildflower.
Plains Coreopsis is one of the most popular annuals in North America, and it’s also one of the easiest to grow. Plant in the spring or fall to see slender thread-like plants with gleaming green stems and tiny leaves. Perfectly spherical, brown-colored buds will form after theseedlings are about 12-inches tall, and soon you’ll have gorgeous sprays of little butter yellowflowers with dark red centers. This species is excellent for cutting, with each stem contributing a flush of miniature blooms to any arrangement; however, do not clip all of them. Plains coreopsis is one of the greatest native annual reseeding plants. This means that even if some plants die due to cold, others will most likely emerge in their place the following spring.
