Namesofflowers.net cites tulipa gesneriana as being the scientific name for tulip. The world’s largest display of tulips is located in Keukenhof near Lisse, Holland. It is open annually from the end of March through mid-May. The display is the result of seven million tulip bulb plantings.
Average tulips grow from 4 to 28 inches tall, and most only have one flower per stem, though some varieties produce up to four flowers per stem. Tulips typically bloom from early spring through summer. Various tulip colors and shades of each color exist, including blue violet, pink, red, lilac, yellow, orange and white, but there are no true blue tulips.
