Perovskia — blue haze and spicy aroma
The plant comes from Central Asia and was opened to the world by the son of Count Rozumovsky, General V.A. Perovsky, bringing from Central Asia to his father’s garden. So, by the name of the discoverer, this fragrant shrub got its unusual name.
Flowering Perovski lasts quite a long time from summer until frost.
At the same time, the inflorescences go into winter sleep, slightly fading, but retaining the attractiveness of the form until spring. Along with cereals, the fragrant bush of Russian sage (another name for Perovsky) is a welcome guest in a snowy garden.
For Perovsky, sunny places are chosen, because in shading the branches are strongly extended and the curtain collapses.
This hardy plant is not afraid of drafts and dry winds, but in winter, snow cover will blow out in windy places and the perennial may freeze.
Considering the fact that Perovsky is comfortable in the conditions of the climatic zone of the range 5-10, it becomes clear why this beautifully flowering and fragrant shrub has become a favorite of European gardeners and is so uncommon in the homeland of its discoverer.

If you are a fan of Pete Oudolf-style flower gardens, Perovsky is your option.
Perovskaya only benefits from landing in arrays.
Given the long lifespan of one bush, perovskia is a welcome guest in borders and hedges.
Perovskia is a dried flower, therefore it will decorate a snow-covered garden until spring.
In a composition with silvery accents, Perovskaya noticeably enhances the effect.
Cuttings are either lignified shoots of the last year, necessarily with a heel, in spring (this information has not been personally verified by me), or green this year (second half of summer). The cuttings are planted in cassettes under the film in a slightly shaded place, monitoring the moderate moisture content of the soil. The young overwinter in a greenhouse.
The soil for the plant should be prepared in advance: lighten heavy soil by adding sand, arrange drainage on clay soil, add slaked lime to acidic soil (this procedure is done at least six months in advance, but in no case immediately before planting). If it is not possible to wait for the deoxidation of the soil, purchased soil is poured into the hole.
Such thorough preparation will justify itself with an incredibly long life (more than a dozen years) of a plant in one place.
An adult perov transplant does not tolerate well: the roots do not have time to increase the depth and the plant may freeze out.
In one place, without a transplant, Perovskaya grows up to 15 years.

Every autumn my grandmother spread a sheet on the stove, poured a mountain of pumpkin seeds on it and dried them. By the spring, these seeds could not be found in the bins — they ate everything during the winter. I didn’t understand such fun, because it was much more convenient to eat sunflower seeds, and pumpkin seeds …
