Any of almost 4,000 varieties of about 100 species of cultivated bulbous herbaceous plants making up the genus Tulipa in the lily family , native to Eurasia.
Among the most popular of all garden flowers, the tulip produces two or three thick, bluish-green leaves clustered at the base of the plant. The usually solitary inverted bell-shaped flowers have three petals and three sepals. Colors range from white through yellows and reds to brown and deep purple to almost black. Streaked blossoms get their streaks from a harmless virus infection that causes the color to disappear in patterns, letting white or yellow show through.
