Tulips(郁金香) are beautiful flowers which were originally grown in Turkey. They were introduced into Europe in the 1500’s. In the Netherlands (荷兰), they became very popular. Tulips became expensive flowers as they took many years to grow from a seed to flower.
Today, in Holland, tulips are highly valued and grown commercially for export. Tulip plants are grown from bulbs(球茎) or seeds. However, those which grow from seeds grow much slower than those from bulbs. The bulbs are planted six to ten centimeters deep in well-drained soil. When the plant grows, roots(根) are formed at the base of the bulb.
