Tulipa - Aliya Shekhmameteva
Tulip is the genus of perennial herbaceous bulbous plants of the lily family (Liliaceae). The center of origin and the greatest diversity of tulip species was located in the mountains of the northern Iran, Pamir-Alai and Tien-Shan. Tulips have been spreading to Spain and Morocco in the west, to Transbaikalia in the east and to Sinai Peninsula in the south for 10 – 15 million years of evolution. In the north population of forest tulip was introduced by human and reached Scotland and the southern coast of Scandinavia.
Tulip is typical ephemeroids, which adapted to life in arid areas with a hot waterless summer. For a short spring period of growth tulip should not finish only blossoming and give a fruit but also accumulate under the ground enough nutrients to lay a new generation of bulbs.
