Coreopsis

The genus Coreopsis (Coreopsis) has more than 100 species - herbaceous annual and perennial plants. They are often grown in cities, in flower beds and in borders, because coreopsis is highly resistant to atmospheric pollution. The leaves of the annual Coreopsis Drummond (Coreopsis drummondii), plants up to 50 cm tall, are dissected into large lobes. Blooms from July to autumn. Inflorescences - golden-brown baskets with a dark center. Reed flowers are narrow, shiny. Coreopsis douglasii (C. douglasii) is a 30 cm tall species with indented leaves. In summer, flat baskets with rare yellow reed flowers bloom. Coreopsis tinctoria is a densely branching shrub up to 1 m high. The lower leaves are simple, the upper ones are dissected. Blooms from July to early autumn in baskets with yellow (3 cm in diameter) reed flowers, dark purple in the middle. Inflorescences of the 'Dark purple' variety have a purplish-brown color. The 'Double' flowers are double, yellow in color. There are other varieties with orange, red-brown or two-colored inflorescences. Perennial species include Coreopsis auricolata (C. auricolata), which grows up to 50 cm in height. Whole, less often three-lobed leaves of light green color are collected in rosettes. In summer, yellow single baskets with purplish-brown median flowers bloom on thin peduncles. Coreopsis large-flowered (C. grandiflora) grows up to 1 m in height, it is the most common species. Large-grained leaves of light green color often grow on flowering shoots. Large golden-yellow numerous inflorescences are formed in abundance at the ends of long peduncles. Flowering lasts from July to late autumn, until October. Coreopsis rosea is a creeping shrub up to 25-30 cm tall. Inflorescences are single up to 2 cm in diameter, pink, on long peduncles. Suitable for semi-shaded areas with fertile soil. Coreopsis whorl (C. verticillata) is a shrub 40-60 cm tall. This species is characterized by whorls formed on the peduncles from thinly dissected into lobules, almost thread-like leaves. The inflorescences are elegant, radiant, shiny, golden-yellow, up to 4 cm in diameter. Blooms profusely in summer.

Cultivation

Coreopsis is widely used for decorating various flower beds, in mixborders, for cutting. Annual dwarf species (Coreopsis Douglas, coreopsis pink 'Dwarf') are grown in pots, perennials-in the open ground, in flower beds. Coreopsis develops well if you keep a distance of 20-30 cm between plants when planting. They are planted in loose soil with high-quality drainage. Before planting, organic fertilizers are applied to the soil at the rate of 30-40 kg/m2. If low-fertile soil is used for cultivation, in the spring and summer period, plants should be fed with a complex mineral fertilizer in the amount of 15 g per bucket of irrigation water. Potting soil is made up of peat and fertile soil with the addition of complex fertilizers at the rate of 15-20 g per bucket of soil. Tall perennial species require supports.

Location

The mandatory condition is open sun; crops growing in the shade are too long. Partial shade, as an exception, is required for coreopsis rosea.

Temperature

All perennial species are resistant to both high and low air temperatures. However, while the plants are young, they should be removed for the winter in a closed, unheated room.

Watering

When growing plants in the open ground, they are watered if there is not enough precipitation, and when growing in pots, watering is necessary when the soil is completely dry.

Care

Remove damaged and dried parts, and in the summer faded baskets.

Reproduction

Annual species are propagated by seeds sown in the ground or greenhouses in spring in April. Finally planted in May. The soil is cultivated and rich in humus. Perennial species are propagated by dividing the bush in spring (in cold climates) or autumn, as well as by seeds and cuttings. On cuttings, growing shoots are harvested in the spring. They root them in a greenhouse.

Diseases

Leaf spots and rust occur in various fungal diseases-it is enough to remove the affected leaves. In viral infections, the tops of plants curl up into a tube. Damaged plants are discarded. Aphids provoke the appearance of spots on leaves, peduncles and buds. Treatment with anti-aphid drugs is required. Some pest beetles eat the leaves. Beetles are usually harvested by hand.

Acquisition

Seeds are easily purchased in stores. When buying, pay attention to the expiration date indicated on the package. Potted plants can also be purchased from nurseries. Choose compact specimens with beautiful green foliage. Make sure that there are no spots on the leaves.
