The history of the appearance of Coreopsis Verticillata
The name Coreopsis verticulata comes from Ancient Greece. It consists of the words koris - bug, and opsis - species. The reason for this strange name was the appearance of the seeds, which reminded the Greeks of a bug.
But the homeland of verticulata coreopsis is the east of North America, where it grows in dry light forests and open pine forests. It has been in culture since 1750. At present, verticular coreopsis has spread to some regions of Africa and South America. It is also found on the territory of Russia.

The petals are with a scalloped edge. The leaves are not as tall as the shoots, their height is half that. This makes the bush not as thick as other varieties, but no less beautiful.
In 2003, Coreopsis verticulata Grandiflora also received the AGM Award from the Royal Horticultural Society of Great Britain.
Planting and caring for Coreopsis whorled
Planting verticulata coreopsis is possible both by seedling method and immediately in open ground. The first method will make it possible to see flowering in the same year.
Seedlings are planted in March-April as follows:
- Sow seeds in a wide, shallow container with fertile soil. Sprinkle on top with a mixture of soil and sand. Drizzle. Cover with foil or a transparent bag to create a greenhouse effect.
- Place the container with seedlings in a warm, bright place. A sill on the south side will work well. Moisten the soil with a spray bottle every few days.
- After the first shoots appear, the film can be removed.
- 2 weeks after emergence, when the plants reach 10-12 cm, the seedlings can be dived into separate containers. Peat pots work best. Seedlings require periodic watering and a lot of light. In this position, the plants will remain until the beginning of June, then they need to be transplanted into open ground.
For whorled coreopsis, open sunny areas or light partial shade are suitable. The soil should be neutral, moist and nutritious, well-drained.
- Moisten the peat pots with seedlings well so that the soil with the plant can be easily removed.
- Prepare a hole: dig a hole 50 cm deep. If the soil is poor, mix the excavated soil with compost and peat in equal proportions. Fill the drainage at the bottom of the hole. On it - a little prepared soil.
- The distance between the holes must be at least 30 cm.
- Remove the plant from the pot along with the soil, carefully place it in the hole, sprinkle with the remaining fertilized soil. Lightly compact the ground, water the seedling.
- To retain moisture in the ground and to avoid weeds, the soil around the plant must be mulched. Rotted sawdust is ideal, but you can use dry grass, hay, straw, bark.
Caring for whorled coreopsis is quite simple, it includes watering, feeding, loosening the soil and protecting against diseases. In hot weather, water the plant 1-2 times a week, in warm weather even less often. Before flowering, coreopsis should be fertilized with a complex mineral composition. Poor soil requires additional feeding before the onset of cold weather. In order for the flowering to be abundant, and the bush to be lush, the soil must be periodically loosened. This will get rid of weeds and oxygenate the land. In addition, for stable flowering, faded buds must be cut off immediately. To prevent the appearance of pests and diseases, plants should be treated with insecticides before flowering.
Before winter, the entire bush is cut to 10-15 cm high. In warm regions, coreopsis winters without additional shelter; in a temperate strip, the bush can be insulated with spruce branches or tops. For the northern regions, so that the plant does not die, it is completely dug up and transplanted into a special container.
Advice! In regions where the winter is snowy, the mulch plant does not need to be covered, since the snow will protect it from frost.
Coreopsis whorled in landscape design
Not every gardener has the opportunity to have large spaces. To decorate a small area, whorled coreopsis can be used as a bright background for lower plants. Group plantings look spectacular both on a flat lawn and in tandem with other bushes, such as spirea and chubushniki.
One of the main advantages of whorled coreopsis is the versatility of cultivation: it looks equally good as small flowers, a single bush or a whole alley
Color differences in varieties of whorled coreopsis make it possible to widely combine the culture with other partners. Low-growing varieties will look appropriate along the border in the foreground. In tandem, you can pick up Veronica, Irises, Geraniums and America for them. The external resemblance to chamomile also gives a lot of options. The alternation of both crops, grouping with bushes or replacing one flower with another after the end of the planting period in one place - everyone chooses for himself.
The use of whorled coreopsis is popular for decorating city roads and in flower arrangements on slopes.
In order for the whorled coreopsis to please with an abundance of flowers, it should be planted on the southern side of buildings, fences, tree and shrub plantations. This culture, planted in street vases, balcony containers, will look like an independent composition. Prolonged flowering will make the whorled coreopsis an important figure on the site.
Advice! The whorled coreopsis is perfect for cutting. Flowers can stand in water for about a week.
