Planting coreopsis, features of growing perennial and annual varieties

The numerous Astrov family also includes the "sunny chamomile" - coreopsis, blooming from mid-summer to autumn. Where this flower is grown, the garden turns into a riot of rich yellow, bright yellow-brown or pink colors. Some species are similar to Gaillardia, because they also come from the North American continent. Others are from Africa and South America.

Description

Coreopsis is a herbaceous perennial plant, although there are also wild shrubs. Its roots are dense, fibrous. Straight stems are densely leafy, actively branching, from 20 cm to 1 m in height. Basal leaves have a large, entire blade. On the stem, the leaves are opposite, pinnately-divided or finger-like. Painted in different shades of green.

On long peduncles there are single inflorescences, baskets of various sizes, depending on the type, their diameter reaches 5-8 cm. Simple and double baskets consist of central small tubular flowers of various yellow, orange and bright brown shades. Extreme ligulate flowers are serrated along the edge, their palette is rich - from sunny yellow to combinations with bright red-brown shades. More intense tones are concentrated in a circular pattern towards the middle of the basket. There are pink and purple flowers. Coreopsis fruits are black achenes with many small grains.

The seeds that look like bedbugs gave the flower its botanical name. From the Greek language "koris" is translated as "bug", and "opsis" is a species. The plant is also called yellow or golden chamomile, Parisian beauty, brown-eyed.

The flowers are sun-loving, undemanding to soil, frost-resistant, withstand summer heat.

Coreopsis is planted in the sun or in light partial shade on loose, drained soils.

• flowers reproduce by self-seeding;
• purchased seeds are best planted for seedlings.

Stagnant water at the roots is detrimental to coreopsis.

Care

Growing from seeds is the easiest way to propagate a flower. Coreopsis is sown in a container in spring. Young plants are transplanted to an open, sunny place. Autumn is also suitable for open field sowing - the seeds are not afraid of frost.

Coreopsis care is simple.

• They are fed with complex mineral fertilizers.
• Only during very frosty winters is coreopsis covered with foliage.
• For fungal diseases such as fusarium and rust, they are treated with fungicides.
• In the case of twisting of the tops and leaves, spotting, with slow development of the plant, it is better to remove it. Most likely, it is a viral disease.
• Aphids are eliminated by spraying the colony with soapy water or garlic infusion.
