Perennial coreopsis: varieties and varieties
Of the more than 100 varieties of coreopsis, no more than 30 are grown in culture.
Coreopsis is a shrub consisting of erect branched stems crowned with inflorescences of yellow, yellow-brown, as well as red and pink flowers of a pinnately dissected or palmately divided form. The most common varieties of perennial coreopsis:
- Lanceolate. A bush up to 60 cm high with yellow inflorescences up to 6 cm in diameter. It blooms for two months starting in July.
Coreopsis lanceolate
- Whorled. A shrub up to 60 cm high that blooms all summer. It is distinguished by light green thin foliage.
Coreopsis Whorled
- Pink. Low (up to 40 cm) shrub with red inflorescences.
Coreopsis Pink
- Grandiflora. This type of coreopsis is distinguished by bushes topped with large flowers of a dark golden or lemon color. The powerful bush can reach up to 1 m in height and blooms for two months from the very beginning of summer.

Planting coreopsis in open ground
When to plant
Perennial coreopsis is planted in open ground in the middle or at the end of May, when warm weather sets in, the ground warms up and the threat of return frosts passes. However, the seedlings must first undergo hardening procedures for two weeks: the seedlings are taken out into the open air every day, gradually increasing the duration of the walk.
How to plant
The coreopsis plant prefers sunny areas, and only some species (whorled and pink coreopsis) can grow in partial shade. The plant needs moderately moist, light, loose, neutral and well-drained soil. As for fertility, some types of coreopsis will not benefit from a high content of nutrients in the soil: this makes them bloom poorly. Before planting, poor soil can be slightly enriched by digging with compost or humus.

Coreopsis seedlings are planted in holes located at a distance of 30 cm from each other. After planting, the surface of the area is compacted and watered.

Planting a plant
It is better to choose a sunny place for planting coreopsis, because in the shade and partial shade this plant does not feel comfortable and may wither. Moderately fertile light soils are well suited for this flower.
Advice. For coreopsis to bloom lushly, the soil must be loose.
It is best to plant perennial coreopsis with seeds. In order for the plant to bloom in the first year of planting, you can sow seeds in winter for seedlings in pots or boxes indoors. And after the end of the frost, transfer and plant the grown seedlings in open ground. There are no special requirements for growing coreopsis seedlings. Just provide your plants with enough light and moisture, and sprouts will follow.
Coreopsis is very easy to grow from seeds.
Coreopsis seeds can be sown directly into open ground both in spring and autumn - the seeds of this plant tolerate low temperatures well. After the first shoots appear, it is necessary to thin them out and monitor them so that weeds do not interfere with the growth of flowers. And also ensure regular watering.

Sowing seedlings
Planting and caring for coreopsis will not require much time or effort from you. Annual coreopsis can be sown in open ground in May, and in a greenhouse in mid-April. Perennial species usually form flowers in the second year after sowing, but if you want to see flowering in the current season, use the seedling method: grow perennial coreopsis seedlings on the windowsill, and then transplant them into the flower garden.

Sowing of coreopsis for seedlings is carried out in early March: the seeds are evenly laid out on the surface of moist, nutritious garden soil placed in shallow containers, pressed against the ground with a board, covered with film and placed for germination in a warm, bright place.

Seedling care
The crops should be ventilated daily, removing condensation from the film. The germination rate of the seeds of this flower crop is very high. Coreopsis from seeds will begin to germinate within ten days, and as soon as this process becomes widespread, the coating from the container can be removed. Caring for seedlings involves watering and carefully loosening the substrate around the seedlings.
Use moderation with moisture, as seedlings may suffer from blackleg, a fungal infection that affects plants during the seedling period and develops in waterlogged soil.
At the stage of development of the seedlings' first pair of true leaves, they are picked out in separate cups. If picking is done in a box, keep a 2 cm step between seedlings and keep in mind that the seedlings will have to be picked again when the seedlings grow to 10-12 cm.
Coreopsis care
Coreopsis is an unpretentious flower. Its advantages include frost resistance and drought resistance. In the middle zone, this flower does not need to be covered for the winter. For abundant and long-lasting flowering, coreopsis needs timely watering. After the plants have flowered, it is necessary to prune them; to do this, cut off a quarter of the plant with garden shears. After pruning, the crop needs to be fed and its flowering will resume.
In summer, protect coreopsis from drying out, and in winter - from exposure to frost.
For the winter, many gardeners advise cutting off the stems at the root. If you live in regions where winters are very frosty, then it is better to cover your flowers with a small layer of foliage or spruce branches.
Advice. Remove faded flowers promptly. This stimulates the appearance of young buds.

Plant propagation
There are several ways to increase the coreopsis population in your garden.
- Division. One of the simplest and most reliable methods of propagation is dividing the rhizome. It is best to divide in early spring, when the soil has already thawed. The soil around the plant must be loosened and the bush must be carefully dug out so as not to damage the rhizome. The root is divided with a sharp knife so that 2-3 buds remain on each division. The cuttings are planted and cared for like ordinary adult plants.
Coreopsis easily survives propagation by cuttings or dividing the bush
- In summer you can propagate coreopsis from cuttings . To do this, in June-July, healthy shoots with several leaves are cut 10 cm below the internode and placed in seedling pots. Leaves must be removed from the bottom of the cutting. You can place up to 3 cuttings in one pot. Pots should be kept in partial shade and watered regularly. In such conditions, cuttings take root very quickly.

Note! Hybrids reproduce only vegetatively, by dividing the rhizome.
Coreopsis Ruby Frost
Other
There are many very popular species of coreopsis that are not rare and are freely available for sale:
- ear-shaped (lat. Coreopsis auriculata) - its inflorescence is formed by flowers with long reed petals rolled into tubes;

Diseases and pests
Coreopsis has a fairly strong immune system and is rarely attacked by pests or diseases, however, there is no 100% guarantee. Known diseases include leaf rust and fusarium. In this case, it is enough to tear off the damaged leaves and you can spray the plant with fungicides. If these remedies do not help, then the bush should be completely removed to prevent infection of other plants in the flower garden.
More often than other diseases, coreopsis overcomes fusarium
The same must be done when viral infections are detected. If the plant is stunted in growth, its tops and flowers curl into a tube - feel free to remove the bush.
Among the pests, coreopsis can be affected by aphids and various beetles. Beetles must be removed by hand, while for aphids you can use specialized preparations or folk remedies.
Possible problems in growing
Under unfavorable weather conditions, the plant can become a victim of fungal infections, as well as invasion of insect pests.
Problems with leaves
The following alarming symptoms can be found on the bushes:
- dry dark spots on the lower foliage - indicate septoria coreopsidis;
- whitish stains are a sign of powdery mildew (Erysiphae cichoracearum);
- white spots on the underside of leaves - downy mildew (Plasmopara halstedii).
If such lesions are detected, spraying with an antifungal drug, for example, Fundazol, should be carried out.
Pests
Most often, the flower is affected by aphids and leaf flies. They are easy to spot on coreopsis; just look closely at the bush. Spraying with a weak soap solution or an appropriate insecticide helps against them.
For reference! For aphids, you can use Fitoverm, Aktar, Iskra-M and other drugs containing permethrin or aversectin.
Diseases
A common disease that affects coreopsis is rust. Its traces are easy to notice on the leaves, which become covered with red spots and then dry out. For prevention, before the buds open, the planting is sprayed with a 1% solution of Bordeaux mixture or another copper-containing preparation.
Signs of improper care
A typical mistake made by those who have not previously grown this plant is excessive feeding. Because of this, foliage grows quickly and abundantly, and flowers are reduced in number and reduced in size.
Note! With excessive flooding, the foliage begins to wither, starting from the tips, and turn yellow.
Caring for coreopsis is not at all difficult; many people believe that it is enough to just plant it, and then it will grow on its own. This is partly true, but still, truly large and beautiful flowers are obtained with regular feeding.

Varietal features
Possessing high winter hardiness, coreopsis grows as a perennial.
A medium-sized shrub with erect shoots and lanceolate light green leaves does not grow higher than 50 cm. It overwinters well even in the middle zone and grows quickly, forming new rosettes.

Terry, they are painted bright yellow and really look like golden fluffy balls. You can admire such beauty for a long time, right up to the frost.
Application in design
Coreopsis is an elegant crop that blooms for a long time, producing a large number of attractive buds. Tall varieties are used to create especially abundant flower arrangements, they are planted in the far corner of the garden, and entire groups are created on lawns. In addition, such crops are good for cutting, since coreopsis flowers can last in a vase for two weeks.
Low-growing flowers are used for planting in front gardens in the form of a border or in groups. Such varieties can be planted in street flower beds, in containers or in balcony baskets at least twenty centimeters deep. It is allowed to replant such a plant even during its flowering period, but it is important to dig up the crop along with a lump of earth and plant it on well-watered soil.
The culture is often used to decorate individual flower beds, mixborders and for cutting. Annual dwarf varieties (Douglas, pink) are planted in pots, perennials - in open flower beds and soil on the site.
