There's more than you think to this pretty and popular flower.
The tulip is one of the most popular garden flowers. Tulips are hardy and require little care. Some types of tulips bloom for years, once established.
Tulips generally are divided into 15 different classes, which vary in appearance and season of bloom. The early bloomers include single early, double early, kaufmanniana, and fosterana tulips. Mid-season bloomers include Mendel, triumph, greigii, and Darwin hybrid tulips. Late or May-flowering types include Darwin, lily-flowered, cottage, Rembrandt, parrot, and double late tulips. Tulips grow in zones 3-8.

The gray-green foliage often is striped with red, brown, or purple, making the greigii tulips attractive even after the flowers have faded. Plant bulbs 8 inches deep and 6 inches apart. Popular varieties include the reliable 'Red Riding Hood.
Other species tulips: This class simply is a catchall for the many less-commonly grown species tulips. All are wild tulips or hybrids. These tulips are hardy, colorful, and especially attractive in rock gardens. Bloom time varies from species to species. Early species such as Tulipa humilis may bloom in February; other species such as Tulipa acuminata wait until May. Some of the most popular tulips in this category include Tulipa tarda, T. chrysantha, T. turkestanica, T. whittallii, and T. eichleri.
Location: Full sun or part shade When to plant: Fall General Instructions: Before you plant tulips, be sure the soil in your planting bed is in good condition. Add a sprinkle of bonemeal to the bottom of each hole. Tulips grow well in almost any type of soil, so long as it is well-drained. Standing water will rot the bulbs. Planting depths vary with each class of tulip. Tulips need cold weather to return year after year. In northern gardens, plant tulips in the fall before the ground freezes. In warmer climates, tulips are treated as annuals. Southern gardeners can buy prechilled bulbs and set them out in the spring, or buy bulbs 8 to 10 weeks before planting time and chill them in a refrigerator. To chase away the winter blues, bring some of your bulbs indoors for forced blooming.
