The parts of a tulip include the tunic, scales, basal stem, roots and flower bud. All tulip flowers consist of six petals, six sepals, six stamens, a single pistil, stigma and a three-lobed ovary.
The tunic is the external covering of the bulb, and the scales are white leaves that serve as storage for food needed by the bulbs to develop and blossom. The basal stem joins the plant’s scales, flowers and roots, which emerge from the basal stem and collect water and nutrients for the plant. The middle of the bulb has an immature and tender flower bud that is sensitive to cold temperature.
The base of the tulip has a group of two to three bluish green leaves. The flowers consist of the petals and sepals, while the fruit contains numerous seeds. They have three different stigmas connected to each other. Most garden tulips reproduce through their scaly bulbs.
Except pure blue, tulip flowers have a variety of colors, including white, yellow, red, brown, purple and black shades. Single-flowered and double-flowered tulips usually bloom in early spring, whereas Mendel and Darwin tulips blossom in midseason. Some of the late-blooming types of tulips include breeders, cottage and lily-flowered tulips.
The tulip belongs to the Liliaceae family. The genus Tulipa is composed of around 100 species that are indigenous to Eurasia.
