Currently, there are around 75 wild species of tulips and 150 species in total with over 3000 varieties.
The word tulip is derived from a Persian word called delband, which means turban. It is generally believed that it was called this due to the turban-shaped nature of the flower. However, this might have been a translation error as it was fashionable to wear tulips on turbans at the time.
Tulips are perennials (a plant that lives for more than 2 years), they bloom in spring, usually for only 3-7 days.
Tulips grow from bulbs and being native to mountainous areas the tulip needs a period of cold dormancy, known as vernalization. So they should be planted in the fall (Autumn) and thrive best in climates with cool springs and dry summers. ~ Bernard
