What to put in a flower bed? Pyrethrum

This ornamental plant will be ideally suited for those who have not enough time for care of a flower bed. Once the planted bushes at the minimum leaving will decorate many years a garden with the whole bouquets of flowers. In decorative garden culture it is used several centuries, and the set of its versions during this time appeared.

Pyrethrum maiden (Pyretrum parthenium) - a perennial plant of family Slozhnotsvetnykh (Asteraceae). The sort Pyrethrum contains about 100 species of plants a sort from the countries of Southern Europe, Asia and America. Call them differently: chrysanthemum (Chrysanthemum parthenium), tanatsetum (Tanacetum parthenium), matrikariya (Matricaria eximia). Some of its types possess medicinal properties. Also the name origin from the Greek word `pyretos` meaning “fever, strong heat“ is explained by it.

Pyrethrum forms a compact, magnificent bush height and with a diameter up to 50 cm with branchy upright stalks. Beautiful carved leaflets are very similar to foliage of chrysanthemums, and not only in an external structure, but also in a smell which is allocated if to rub a leaf fingers, or after cut of flowers. On a coloring leaves are is yellow - green, light-green and is dark - the green, sitting on scapes about 7 - 10 cm long

Flowers tower over a bush, forming the real bouquet from small inflorescences - baskets with a diameter from 1,5 to 3 cm, collected in a shchitkovidny inflorescence. Regional flowers - reed, central - tubular, yellow. There are forms with simple baskets as small romashechka, and are with terry. There is a look having only yellow tubular flowers, forming inflorescences as if of small buttons.

Pyrethrum approximately in three months after crops of seeds blossoms. Blossoms plentifully in summer months, can repeatedly blossom and in the fall. For this purpose it is necessary to cut off deflowered tsvetonosa during summer blossoming, without having allowed to be tied by seeds. Seeds - small rhabdoid semyanka, as at camomiles, beige coloring. They keep the viability for 2 - 3 years.

Pyrethrum is very unpretentious and steady against conditions of growth . Loves the sun, but perfectly grows also in a penumbra, and even in a shadow, however, at the same time it is a little extended. Very much holodostoyek, easily maintains small frosts (to - 4 - 5 °C). To the soil it is not really exacting, well grows in any place, except for frankly poor sandstones and places which are constantly flooded by water. On the fertile friable soil forms magnificent large bushes with big bouquets of inflorescences.

The main leaving consists in regular waterings, especially in droughty weather, and in need of podkormka. Only young plants at the initial stage of growth need weedings. In the subsequent they independently suppress growth of weeds. After plentiful waterings and rains it is desirable to podrykhlit the soil to prevent emergence of a crust on the Earth`s surface and to improve aeration of roots.

From wreckers on pyrethrum the black plant louse meets, it is enough to process its one of suitable preparations or just to remove the struck plant from a site.

Adult plants well transfer change at any stage of development on condition of preservation of an earth lump on roots. Pyrethrum division of the expanded bushes and seeds breeds. If not to cut off deflowered arrows, then he easily breeds self-sowing. It even happens favourably: it is less than efforts with cultivation of seedling, it is enough to replace young shoots to the right places in spring.

If it is necessary to put a new grade, then it is grown up through seedling . Seeds sow in March in boxes with a friable fertile soil, evenly scattering them on the humidified surface and having powdered from above with the earth a layer no more than 5 mm. In heat they quickly enough sprout. After that the box with seedling is placed in the light, but not hot place with a temperature not above 20 °C. If seeds on the soil were distributed not densely, then sword-play can be not done before planting of seedlings in an open ground.

At their zagushchenny landing dive after emergence of 3 - 4 real leaves. In an open ground young seedlings land in May after a hardening. Though it will be more correct to tell: after schooling to open air and the sun. Because the cool to them is not terrible, and here sunshine can do irreparable harm. That it did not occur, after disembarkation to the street the seedling should be pritenit surely from the sun for the first 1 - 2 weeks. Distance between plants about 30 cm

leave Pyrethrum quite perhaps to grow up as a perennial plant. Cut off deflowered escapes in the fall, mulch the soil around bushes and cover them with fir-tree fir twigs. In such look they perfectly winter in climatic conditions of a midland.

Low grades of pyrethrum are used as borders on city beds, in street flowerpots. Grades with terry and spherical inflorescences are very much appreciated. Grades with it is yellow - are used by green coloring of foliage as beds and flower beds, dekorativnolistvenny at a frame, flower shooters in such cases at them delete. Beautifully the pyrethrum put randomly on all garden under fruit-trees and near ornamental shrubs looks.
