You know it’s spring when those long, lovely tulip stems start peeking out of the ground! There are more than 1,000 different tulip species, and each of them brings its own touch of charm to springtime. In fact, so many species exist that scientists have grouped them into 15 main categories of tulip types, just to keep them in order! So in honor of our Tulip Spectacular, we’re celebrating the warmer weather by picking our six favorite tulip types. Read on to find out what makes each category of these spring blooms beautiful and unique!

Tulip Type No. 1: Single Tulip

The beautiful simplicity of these tulips is what makes them a favorite among gardeners and florists all over the world. In fact, our floral designers at 1-800-Flowers.com use Single tulips to create all of our spectacular tulip arrangements. Whether they’re solid-colored or bicolored with two contrasting hues, these flowers bring a bold pop of color to any home or garden. They can be found in virtually any hue, including red, yellow, orange, pink, purple, blue, white and black. We love the gorgeous, deep color of the purple tulip so much that we even chose it as our signature flower!

Single tulips come in two varieties: early-blooming and late-blooming. Early bloomers start to spring up in late Mach and can grow up to 17 inches tall, and each flower can expand up to 3 inches wide. On the other hand, Single Late tulips typically bloom in May and can grow up to 30 inches tall, with a 3-inch-wide flower. Some of the most popular Single Early tulips include the Purple Prince, Diana, Prince of Austria, Cardinal Rampolla, Lac van Rijn and Keizerskroon. For Single Late tulips, favorites include the Antoinette, Blushing Lady, Queen of the Night, Avignon, Dreamland and Zomerschoon.
