Achillea

Yarrow (Achillea) is a genus of numerous perennial herbaceous and semi-shrubby plants. They are distributed in the temperate zone of the Northern Hemisphere, many in the mountains. Yarrow species easily interbreed with each other. Baskets are small, multi-flowered, usually in a common thyroid inflorescence, less often single. Mace-shaped yarrow (Achillea clavinae) is an Alpine species with a height of 10-20 cm. Peduncles are poorly branched. The leaves are silvery green. The marginal reed flowers of the baskets are white, the median ones are white, but darker than the reed ones. The baskets, in turn, are collected in apical shields and are kept on the plant throughout the summer. Yarrow meadowsweet (A. filipendulina) - a species with a height of 90 cm to 1.5 m. The leaves are toothed pubescent, brown-green in color. In summer, lemon-yellow baskets collected in dense shields bloom in large numbers. Common yarrow (A. millefolium) grows up to 1 m in height. The leaves are dark green elongated biconvex, lanceolate in shape. The flowers form compact baskets of white or intense and pale pink color, collected in flat dense corymbs. Musk yarrow (A. moschata) is a creeping Alpine species. Peduncles are pubescent, pinnate leaves of bright green color. From July to September, white baskets bloom, collected in sparse shields. Prefers calcium-poor soils. The noble yarrow (A. nobilis) is a species that grows to a height of both 20-30 and 60-80 cm. The bushes grow up to 50-60 cm in diameter. The creeping stems are very branched. The leaves are lanceolate and pointed. Baskets of yellowish-white color are collected in dense shields. The plant prefers calcareous soils. Yarrow felt (A. tomentosa) is a very easy-to-cultivate species. Plant height 15-20 cm. The leaves are bluish, slightly dissected. The flowers are collected in wide voluminous inflorescences. In addition to these species, hybrids with yellow or white flowers in very dense inflorescences are also grown.

Cultivation

Grown outdoors: in flower beds, borders, and rock gardens, in groups or together with other perennials. Tall varieties can be grown as flowers for cutting. Use well-drained soil, feed it every year in the spring. It is better to grow in a well-lit sunny place. Between plants leave a distance of about 25 cm for low species and up to 50-60 cm - for tall plants.

Location

Yarrows prefer a place in the open sun.

Temperature

Not capricious to air temperature, resistant to temperature fluctuations.

Watering

They consume little water. During planting, the ground around is spilled with water, and then it is enough to water several times-on windy days and in a drought.

Care

Remove faded inflorescences and damaged parts.

Reproduction

It is easily propagated by seeds and dividing bushes in the spring. The resulting individual plants are immediately planted directly into the ground. In spring, seeds are also sown in containers-under glass or plastic. After the seedlings grow up, they are transplanted into boxes with loose earth, add a full mineral fertilizer of prolonged action (with a gradual release of nutrients). Then once again they are transferred to a box or cups, and then in the fall or next spring to a permanent landing site.

Diseases

The most common yarrow disease is powdery mildew caused by Erysiphe cachoracearum, in which the stems and leaves are covered with white mold. The disease is controlled by using dinocap or sulfur-containing fungicides.

Acquisition

Seeds are easy to find on sale everywhere: from the gardening center to the supermarket. In spring, you can buy seedlings in cellular containers - in flower nurseries, flower shops and gardening centers.
