Polygonum affine is a genus that includes about 300 species of annual and perennial grasses, semi-shrubs and even lianas.
In nature, it can be found on meadows, in forests, highlands and near water bodies all over the world. Of this variety, only 20 varieties are used to decorate the garden.
The culture has a strongly creeping root and straight, protruding or curly knee-like stems with alternating simple lanceolate-ovate leaves.
Small flowers are organized into cyst-shaped or petrified inflorescences, on which fruit-peanuts with many seeds are formed.
Among the varieties of this plant that have taken root in our area, the first to use in the crop was a mountain relative who came to us from Nepal, and twice twisted (snake) species.
Later, various species from Far East Asia were brought in. For example, the Alpine mountain (photo 1), whose bush can grow to one and a half meters in height, became particularly popular. It has many branched stems and lanceolate ovoid leaves.
Powerful thickets also form unpretentious species: Variable and Weyriha (photo 2), growing up to two meters, and almost three meters of Sakhalin variety.
A little more miniature will be a perennial lively mountain – up to half a meter high. The height of a relative highlander varies within 20-25 cm, and the head one (photo 3) is spread over the ground and grows up to 10-15 cm.
Among the few requirements of the Polygonum affine to the place of growth are a moderately humid area in the shade and non-oxidized soil. It is undesirable to overwet the soil (especially for a relative and sprayed mountaineer), although snake species can also develop when groundwater is close.
Polygonum affine is very drought-resistant and can winter without shelter, so it is considered one of the most unpretentious cultivated plants. However, such unpretentiousness can even turn it into a weed, as aggressive growth disrupts landscape design and displaces less strong representatives of flora on the site.
All these soil-covering plants reproduce by division and root progeny, and some also by seeds. In one place, a fast-growing crop can grow for 6-10 years and can easily carry a transplant with an earthy coma.
Immediately after winter, the appearance of the shrub may not be very decorative, but it is not worth trimming old shoots. Pretty soon narrow oblong leaves appear on them, and in May – pink flowering candles.
At the peak of decorative culture gets in early June, when the inflorescences change pale pink to red, and then completely burgundy to frost.
