The tulip (Tulipa gesneriana) belongs to Liliaceae (the Lily family). It is a perennial herb that is native from East Asia to Central Asia and North Africa. This herb was started to cultivate in the middle of 16th century. It was introduced into Japan in the latter half of 19th century, and had been cultivated the last days of Meiji Era. The red, yellow, white, or pink flowers come from April to May. There are many flower types, such as fringed, doubled or parrot flower. There is also an "Ice tulip" that you can enjoy outdoors from winter to early spring. The tulip bulbs are refrigerated by a special method, and the temperature difference from the outside temperature gives a simulated experience of winter and adjusts the flowering time. Since the temperature is low in winter, it is characterized by long-lasting flowers and long flowering times.
