TULIP

Tulips are perennials grown from bulbs. Depending on the species, tulip plants can grow as short as 4 inches (10 cm) or as high as 28 inches (71 cm). The tulip's large flowers usually bloom on scapes or subscapose stems that lack bracts. Most tulips produce only one flower per stem, but a few species have up to four flowers. The colourful and attractive, cup-shaped flower has three petals and three sepals, which are often termed tepals because they are nearly identical. These six tepals are often marked near the bases with darker colorings.

The flowers have six distinct, basifixed stamens with filaments shorter than the tepals. Each stigma of the flower has three distinct lobes, and the ovaries are superior with three chambers.^{[further explanation needed]} The tulip's fruit is a capsule with a leathery covering and an ellipsoid to subglobose shape.^{[further explanation needed]} Each capsule contains numerous flat, disc-shaped seeds in two rows per chamber.^[3]These light to dark brown seeds have very thin seed coats and endosperm that does not normally fill the entire seed.^[4]

Tulip stems can have up to a few leaves, with larger species tending to have multiple leaves and smaller species having none. Plants typically have 2 to 6 leaves, with some species having up to 12 leaves The tulip's foliage is strap-shaped with a waxy coating and alternately arranged on the stem. These fleshy blades have a light to medium green color and are linear to oblong in shape Tulip bulbs usually grow on the ends of stolons, and the bulbs' tunicate (dry and papery) coverings may or may not have hairs.

ORIGIN OF THE NAME.

Although tulips are often associated with The Netherlands, commercial cultivation of the flower began in the Ottoman Empire. The tulip, or lale (from Persian لاله, lâleh) as it is also called in Iran and Turkey, is a flower indigenous to a vast area encompassing parts of Africa, Asia, and Europe. The word tulip, which earlier appeared in English in forms such as tulipa or tulipant, entered the language by way of French tulipe and its obsolete form tulipan or by way of Modern Latin tulīpa, from Ottoman Turkish tülbend ("muslin" or "gauze"), and is ultimately derived from Persian dulband ("turban").

CUULTIFATION

Tulips are indigenous to mountainous areas with temperate climates and need a period of cool dormancy. They do best in climates with long, cool springs and early summers, but they can even grow in cold and snowy winters. Although perennials, they are often replanted annualy in warmer areas of the world.

The bulbs are typically planted around late summer and fall in well-drained soils, normally from 4 inches (10 cm) to 8 inches (20 cm) deep, depending on the type planted. In parts of the world that do not have long cool springs and early summers though, the bulbs are often planted up to 12 inches (300 mm) deep. This provides some protection from the heat of summer and tends to force the plants to regenerate one large bulb each year instead of many smaller non-blooming ones. This can extend the life of the plant in warmer areas by a few years, but it does not stave off degradation in bulb size and the eventual death of the plant.
