Tulips originated in central Asia, including China and Siberia. They were first bred in Persia in the 12th and 13th centuries. Tulips were brought to Europe in the 16th century, and became especially popular as a trade commodity in Holland.
Tulips have two or three thick leaves that cluster near the bottom of the plant. The flowers are solitary and bell-shaped.
Tulips grow in many colors, including white, yellow, pink, red and purple, but not blue. Red tulips are the most popular.
Tulips flower each year for several years, remaining underground as bulbs when they are not flowering. They can be planted as seeds or bulbs.
Tulips thrive best in climates with very cold winters and dry, hot summers.
Fusarium is one type of disease that affects tulips. It is a fungus that causes a white or tan mold to develop on the bulb.
