Tulpan (lat. Túlipa) is a genus of perennial herbaceous bulbous plants of the Liliaceae family, which includes more than 80 species in modern taxonomy [⇨]. The center of origin and the greatest diversity of tulip species is the mountains of northern Iran, the Pamir-Alai and the Tien Shan. Over 10-15 million years of evolution, tulips settled to Spain and Morocco in the west, to Transbaikalia in the east and to the Sinai Peninsula in the south. In the north, human-introduced forest tulip populations reached Scotland and the southern coast of Scandinavia [⇨].
All tulips are typical ephemeroid geophytes adapted to life in mountainous, steppe and desert areas with hot dry summers, cold winters and short warm and humid spring. The development of a tulip from seed to flowering plant takes from three to seven years [⇨]. A change of generations of bulbs, unlike daffodils, occurs annually [⇨]. During a short spring growing season, the tulip blooms [⇨], bears fruit [⇨] and lays young bulbs underground, and the faded bulb dies [⇨]. In the period of summer dormancy, and in some species in winter, inside the bulb, the rudiments of the shoot and flower of the next year are formed. In autumn, the bulb gives root [⇨] and completes the laying of the fruiting shoot [⇨].
