The plant of the aster of the perennial reaches its height120-130 cm. The rhizome is located horizontally. The strongest subterranean shoots come to the surface of the soil and give 3-4 sheets that go under the winter. These young shoots form rhizomes with numerous roots. For several years of growth in one place the old rhizome dies off, and the center of the bush rises.
The easiest way is to reproduce asters by dividing a bush,Which can be produced both in autumn and in spring. One kidney and several roots are sufficient for the development of a new plant. The plant tolerates the division and transplantation painlessly.
It is possible to propagate asters and seeds, whichAre sown immediately after harvesting to a depth of no more than 0.5 cm. In the spring the seedlings are dived, but only in the autumn are planted in a permanent place. Young plants bloom for the second year.
