Tulip
Spring-blooming bulbous geophytes with showy, colourful flowers.
Tulips are spring-blooming perennial herbaceous bulbiferous geophytes in the Tulipa genus, part of the lily family Liliaceae. Their flowers are usually large, showy, and brightly coloured, generally red, orange, pink, yellow, or white, often with a different coloured blotch at the base of the tepals. There are about 75 species divided among four subgenera. Originally found from Southern Europe to Central Asia, tulips have been widely naturalised and cultivated since the seventeenth century, becoming associated with the Netherlands as a major producer for world markets.

Lore & Background
Tulips were originally found in a band stretching from Southern Europe to Central Asia, adapted to steppes and mountainous areas with temperate climates. The Persian and Turkish people were the first to cultivate tulips, with cultivation dating back to 10th-century Persia. By the 15th century, tulips were among the most prized flowers, becoming the symbol of the later Ottomans. Tulips were frequently depicted in Dutch Golden Age paintings and have become associated with the Netherlands ever since.
Reader's Guide
Tulips hold significance as both ornamental garden plants and cut flowers, popular throughout the world. Their classification has been complex and controversial due to variability within populations and a long history of cultivation. The name 'tulip' is thought to be derived from a Turkish word for turban, which the flower may have been thought to resemble. In the seventeenth-century Netherlands, an infection by the tulip breaking virus created admired variegated patterns, though truly broken tulips are no longer cultivated; the closest available specimens are part of the Rembrandt group. Breeding programmes have produced thousands of hybrids and cultivars. Tulips are also notable for their phytochemistry, containing tulipanin, tuliposides, and tulipalins, which can cause allergic dermatitis and are toxic to horses, cats, and dogs. The great majority of tulips have no discernable scent, though a few species and cultivars are scented.

Frequently Asked Questions
What is a tulip?
A tulip is a spring-blooming perennial bulb plant in the genus Tulipa, belonging to the lily family (Liliaceae). It produces large, brightly coloured flowers in reds, oranges, pinks, yellows, or whites, often with a contrasting blotch at the base of the tepals.
Where do tulips originally grow?
Tulips are native to a broad stretch running from Southern Europe through to Central Asia. They were first cultivated as far back as tenth-century Persia before spreading into widespread European horticulture.
How many tulip species exist and how are they grouped?
There are roughly 75 recognised tulip species, divided into four subgenera: Clusianae, Orithyia, Tulipa, and Eriostemones.
Why are tulips so strongly linked to the Netherlands?
Although tulips originated in Southern Europe and Central Asia, the Netherlands became their dominant global producer starting in the seventeenth century. The country's climate and commercial infrastructure made it the world's primary source of cultivated tulips for international markets.
What makes tulips botanically distinct?
Tulips are herbaceous geophytes that store energy in underground bulbs, allowing them to die back each summer and re-emerge each spring. Their showy, often multi-coloured flowers and perennial growth habit set them apart within the lily family.
