The annual variety of Coreopsis, like its perennial sisters, has been hybridized to generate plants that are more compact, floriferous, and colorful than the wild parent. ‘Salsa,’ a compact 15″ tall variety with yellow and red bicolor blooms, and ‘Jive,’ a petite selection with bicolor blossoms with dark red centers and white margins on the petals, are two very appealing hybrids.
Coreopsis is a multi-purpose plant that works well in beds and borders, cottage gardens, and naturalized areas.
- For a splash of color, scatter them throughout the ornamental garden.
- To create texture to your environment, combine them with the spikier shapes of Veronica, Liatris, and Salvia.
- For a traditional color combo, pair the bright, joyful yellow options with contrasting blues or purples.
- In an informal meadow setting, combine Echinacea (coneflower), Hemerocallis (daylily), Monarda (beebalm), Achillea (yarrow), and Gaillardia (blanket flower).
- To soften the appearance of bold-leaved plants, use airy threadleaf species.
- In a seasonal container garden, combine annual species with tall spiky accent plants and trailing “spillers.”
- Plant skippers, buckeyes, painted ladies, and the occasional monarch in butterfly gardens to attract them.
- Full sun is preferred by Coreopsis (six or more hours of direct sun per day). It can grow in part shade, but it will not flower as well.
- Watering: Keep newly planted Coreopsis well watered until it establishes itself. It is drought hardy once established, though it will welcome a drink of water during really hot and dry conditions. C. rosea is an exception, as it prefers soil that is continually moist.
- Fertilizer: Fertilizer isn’t always necessary, and it might actually make the plant seem lanky.
- Apply a little application of a balanced granular 10-10-10 formula in early spring if you fertilize at all.
- Soil Preparation: According to research, Coreopsis thrives in sandy, well-drained soil. However, as long as the soil is sufficiently drained, it will withstand most soil conditions. In the winter, when our heavy, clay-based Virginia soils hold moisture, this is crucial. To fix the problem, add compost to flower beds to increase drainage and mound the planting site slightly to allow the soil to drain more quickly.
- Deadheading: While it may not be your favorite way of spend your free time, deadheading promotes more Coreopsis blooms throughout the growth season.
- It also prevents the plant from devoting all of its energy to seed production.
- Remove both the spent bloom and the flower stalk when deadheading.
- You’ll have a much neater plant if you cut the stems back to the foliage.
- Shearing: When flowering slows down in the middle of the summer, shear the plants by 25% to 50% to induce re-blooming. Shearing will result in the loss of some flowers and buds, as well as spent blooms, but the plant should be back in full bloom in a few weeks.
- Dividing: Divide every two or three years in the spring or early fall to retain vitality. Water newly transplanted specimens on a regular basis until they establish themselves.
- Late Summer Care:Coreopsis flowers so profusely that it exhausts itself. Late in the summer, trim the plants back by half or more to help prevent this. This could boost its chances of surviving the winter.
- End-of-Season Care: Coreopsis does not need to be pruned back in the fall, which will please the lazy gardener.
- In fact, the stems aid in the winter protection of the crowns.
- If you prefer your landscape to be neat and tidy, cut the stems back half way but leave 6 to 8 inches of stems in situ. Clean the crown of the plant of any dead leaves or other debris that could harbor pests, then sprinkle a layer of compost around the plant. A small layer of mulch spread around but not over the crown in late fall will help insulate the roots from winter temperature extremes.
- Seed The majority of Coreopsis species may be cultivated from seed, which germinates quickly and produces plants that are generally true to type.
- Many of the hybrids are sterile, meaning they don’t reproduce. To acquire plants that are true to type, Coreopsis selections with sterile blooms must be grown vegetatively (either by division or cuttings).
- Early in the spring, before the leaf develops, divide the plants.
- This procedure is applicable to both straight species and cultivars.
- Stem cuttings can be used to propagate C. grandiflora selections vegetatively.
- They’re simple to root as long as you have adequate plant material to conduct a stem cutting.
Coreopsis is relatively trouble-free when grown in ideal conditions (full light and well-drained soil). Powdery mildew is the most common condition, however it is rarely severe enough to require treatment. Slug and snail damage, as well as fungal patches and powdery mildew, can all be difficulties for this plant if the weather is consistently wet. Crown and root rot can be caused by poor drainage.
Accept the fact that Coreopsis is, for the most part, a short-lived species.
This is especially true in the case of C. grandiflora.
Many promising new hybrids, on the other hand, have been designed with the purpose of increasing its reliability.
Changing the environment in which this plant is grown can also extend its life and prepare it for winter survival.
Amending and slightly mounding the soil to enhance drainage, deadheading on a regular basis, dividing the plant every two or three years, and leaving the foliage in place over the winter to protect the crown from freezing temperatures are just a few examples.
Also, keep in mind that rhizomatous species are better equipped to endure soil moisture extremes than clumping species.

Third Edition of Herbaceous Perennial Plants: A Treatise on Their Identification, Culture, and Garden Attributes (Armitage, Allan M., 2008)
Is coreopsis plant invasive?
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.
Does coreopsis multiply?
Although perennial coreopsis are tough plants, they only last three to five years on average. A decrease in flowering indicates that it’s time to divide the plants (or start over from seed) in order to propagate them.
What perennials can be planted together?
Plants, like people, live longer lives when they are accompanied by others. These companions should complement each other and bring out their greatest features. Choosing which flowers will get along the best can require a lot of trial and error. You can’t go wrong with these expert-recommended floral combos.
Geraniums and Roses
Roses are available in a wide range of colors. They are attractive, but they are susceptible to disease and are frequently devoured by aphids and other pests. Roses do best in sunny areas with well-drained soil. They should do the same with their partner plant.
Geraniums are known for their long-lasting color. Throughout the spring and summer, they have lacy, dark green leaves with a variety of colourful blooms. When used in conjunction with roses, their scent deters pests.
Roses and geraniums are a classic combination. Geraniums fill up the gaps between the thorny stalks of the roses. This interaction is beneficial not just in terms of pest control, but also in terms of how the beauty of each flower complements the beauty of the other.
Coneflowers and Black-Eyed Susans
Another traditional garden combo is coneflowers and black-eyed Susans. These flowers are simple to care for. They can tolerate high temperatures and humidity, as well as dry soil and partial shade. From late spring through early October, coneflowers and black-eyed Susans bloom.
Coneflowers can reach a height of three feet. Their purplish-pink blossoms attract butterflies and other pollinating insects. With contrasting pink and yellow tones, these blossoms will bring beauty to your yard all summer.
Astilbe and Hosta
Astilbe is a perennial flower that thrives in a damp, shady environment. Astilbe features fern-like foliage and delicate spirelike red, pink, white, and purple blooms. It flourishes in soil with a lot of organic matter.
Hostas are shade-loving perennials as well. They’re mostly grown for its brightly colored foliage. They can range in size from little plants to four-foot-tall plants. A hosta flower with a long stem hangs atop the plant and resembles a lily.
In shaded areas, astilbe and hosta planted together can create a splash of color. Their brilliant flowers and foliage brighten up your garden’s dull regions.
Hydrangeas and Daylilies
Hydrangeas bloom from late spring through early autumn. This flowering shrub can reach a height of 15 feet. They thrive in soil that contains a lot of organic matter. It is critical to have soil that drains well. Hydrangeas, while not common, can attract pests if they are stressed.
Daylilies are one of the most adaptable flowers, growing in practically any habitat. Daylilies, like hydrangeas, prefer moist, well-drained soil. Aphids and other beetles are naturally repelled by them.
Making a border wall with hydrangeas and daylilies is a terrific way to add interest to your garden. The late spring blooming time of hydrangeas contrasts with the mid-summer blooming time of daylilies, creating a tangle of color against a backdrop of green greenery.
Daffodils and Amsonia
One of the best companion plants is daffodils. Daffodils are one of the first flowers to bloom in the spring and provide a splash of brightness. They can be planted in a flower garden that is already established. Daffodils discourage insects, deer, rabbits, and other garden pests.
Daffodils and Amsonia grow in the same climate. Their blue blossoms bloom about the same time as the daffodils. Larger Amsonia plants can help disguise the dark leaves left behind when daffodil blossoms fade when planted with daffodils.
In the fall, the leaves of Amsonia turn a golden yellow color. The late color shift adds a lovely touch to the falling leaves.
Hibiscus and Bee Balm
Another form of flowering shrub is the hibiscus. Their enormous blossoms, which require continuous water and full sun, attract butterflies and hummingbirds. You can reduce the amount of water you need to water them by using moist soil.
Bee balm flowers are daisy-shaped and feature tubular petals. Colors vary, but red, pink, white, and purple are the most prevalent. They attract butterflies and hummingbirds, just like hibiscus. Bee balm, which prefers moist soil as well, is an excellent companion to the hibiscus plant.
Iris and Phlox
Late in the spring, iris blossom. Hummingbirds and butterflies are drawn to these brilliantly colored flowers. Full sun is ideal for iris blooming. They prefer nutrient-rich, damp soil. Irises look best with flowers that bloom later in the season. You can, however, combine them with spring blossoms in opposing, complementary colors.
Phlox are perennials that grow to be quite tall. In the summer, their clusters of white, purple, or pink blooms appear. They, like irises, enjoy the light and require hydration. They’re a good match for irises because they bloom after the irises have finished blooming for the season.
Tulips and Hyacinth
In the early spring, tulips are one of the first flowers to bloom. These bright flowers prefer a dry, neutral soil and afternoon sun. Tulips come in a variety of hues and are known for their cup shape.
Hyacinth is a flower that blooms in the spring. They have a strong, long-lasting aroma that attracts a variety of pollinating insects. They, like tulips, prefer a lot of sunlight and a neutral, dry soil. Flowers on hyacinths have prickly stalks. When hyacinth is combined with cupped tulips, the spiky blossoms add texture to your yard.
Daisies and Petunias
Daisies bloom from late spring until early autumn. They grow well in nutrient-rich, well-draining soil. They come in a variety of hues and thrive in direct sunlight. Their yellow centers are the most well-known feature.
Petunias, like daisies, require full sun and nutrient-rich, well-draining soil to thrive. They bloom a few days earlier than daisies. Their trumpet-shaped flowers appear in a rainbow of colors.
You must consider the hues of daisies and petunias while planting them together. Both flowers are available in a variety of hues. Colors that complement each other, such as white and purple, are a good choice.
Merrybells and Virginia Bluebells
This traditional mix creates a vibrant yellow and blue color scheme that is sure to stand out. Merrybells bloom in early April and can grow to be more than two feet tall. Their leaves have a withered aspect to them.
Bluebells can reach a height of 18 inches. As the bluebell flowers age, they turn pink. A two-tone effect can be achieved by shifting from blue to pink on a single flower. Because they mimic the wilted appearance of the yellow Merrybells, they go well together.
Marigolds and Lavender
In the summer and early fall, marigold flowers give charm to your landscape with their vibrant orange color. The marigold’s unique perfume deters rabbits, beetles, aphids, and other pests, as well as being attractive. Marigolds can withstand drought. They thrive in hot, sunny conditions.
Lavender can reach a height of one to three feet. Lavender’s purple contrasts beautifully with marigolds’ orange. Lavender, like marigolds, is drought resistant. Lavender attracts bees and butterflies, which aid in pollination of its surroundings.
While the aforementioned combinations work well together, each flower on this list can also be matched with others. Tulips and daisies complement one other nicely. Lavender goes well with practically anything. The most enjoyable aspect of gardening is deciding which flowers to grow.
It’s critical to select flowers that thrive in similar environments. It’s also important to represent your individuality. This list can be used as a starting point for developing your creativity.
How far apart do you plant coreopsis?
While coreopsis may live in less than full sun, it will likely blossom poorly if at all. Plant it where it will receive at least 6 to 8 hours of direct sunlight each day. The broad-leaved tickseed (latifolia) is an exception, as it enjoys part to full shade.
Soil: Coreopsis favors well-drained soils and can survive drought once established. Threadleaf coreopsis, for example, may grow in dry, rocky soil. Heavy, moist soils are not their favorite. This will have an impact on their ability to survive the winter. Compost can be added to clay and damp soils, or beds can be elevated with superior soil on top. Creeping species have a better chance of overwintering in thick, damp soils than clumping species.
While spacing varies depending on the species and cultivar, most people can get away with 12 to 18 inches between plants.
Planting: Because these are typically found in pots, you can start planting the perennials as early as early spring (they may withstand mild cold) and continue until early fall. Plant the annuals in the spring so you may enjoy their blooms all year.
Are coreopsis Weeds?
Tick weed is a blooming perennial native to North America that is also known as tickseed or coreopsis. Summer through early fall, the plants grow up to 4 feet tall and produce yellow daisy-like flowers. Tick weed is popular for its ease of care, steady performance, adaptability to a variety of growing situations, and gorgeous blossoms. Once established, tick weed is relatively low maintenance. Tick weed grows in USDA Zones 4 through 9 and requires minimal maintenance in most parts of the country.
How do you stop coreopsis from spreading?
After each use or between plants, disinfect pruning or cutting tools by immersing the cutting area of the instrument in rubbing alcohol or washing it off with a bleach solution. This washing aids in the prevention of disease transmission between the coreopsis and any other plants that the cutting tool may come into contact with.
Can coreopsis be divided?
Divide Coreopsis (Coreopsis species) in the spring, late summer, or early fall. Cornflower (Centaurea species)Division is required every 23 years. In the spring, divide the crops. Divide daylilies (Hemerocallis species) in the spring or late summer/early autumn.
What can I plant with Zinnia?
The zinnia is a plant genus that belongs to the sunflower family. It’s extremely popular in the Southwest and is grown all the way down to South America. In sections of Mexico, the zinnia is likewise fairly varied.
The plant is arguably best known for its long-stemmed flowers that grow away from the rest of the plant. They are available in a variety of hues. Johann Zinn, a well-known botanist, was the inspiration for the plant’s name.
In the summer garden, the zinnia is typically regarded as the most hardworking flower. You’ll want plants in your garden that offer three major features during the warmer months.
You’ll want your plants to be vividly colored and heat and drought tolerant. You’ll also want to reduce the amount of effort required to cultivate the plant because many individuals are concerned about maintenance.
The zinnia enjoys working at a breakneck pace. It’s one of the most straightforward flowers to grow. You don’t even need to spend much time preparing the soil before you start planting.
The zinnia, on the other hand, prefers a little of well-drained soil. It thrives in any location that receives adequate heat. However, you do not need to be concerned about your zinnia flourishing alone in your garden.
The zinnia can be grown from a variety of different species. Here are just a few of the various plants that can be grown with zinnias.
What can I plant with primulas?
Primula vulgaris is a common flowering plant. It looks great planted with daffodils, cyclamens, and snowdrops, and the flowers are fantastic for pollinators. In partial shade, grow it in wet, well-drained soil.
What plants go well with clivias?
The attention is drawn to the traditional, tropical-looking orange blossoms or bright red, pink, yellow, or cream but the glossy, dark-green, strappy leaves that grow in stunning arches are an architectural element for all seasons. The leaves appear in an alternate pattern and arch perfectly symmetrically over one another, creating a highly formal appearance.
By planting in the same plot, you may use the leaves as a backdrop to maintain your dry, gloomy location in bloom throughout the spring, summer, and autumn:
