description_en: Genus of about 100 species of bulbous perennials found in usually hot, dry situations, from sea level and steppes to alpine areas, in temperate Europe, Asia and the Middle East, although they are at their most diverse in C. Asia. Tulips have linear to broadly ovate, hairy or hairless, sometimes channelled or wavy-margined, mostly mid- or grey-green leaves; they are generally borne at the base, although in some species and cultivars they are arranged alternately on the usually hairless, sometimes hairy or downy flower stems, and decrease in size up the stem. The upright, terminal flowers, each with 6 tepals (often referred to as petals), are borne singly or in clusters of up to 12. Tulip cultivars have single or double flowers, mainly ovoid or goblet- to bowl-shaped or lily-like, sometimes fringed (see panel below), and are available in a wide range of single, mixed, or variegated colours. Variegation (i.e. breaks in colour) may be caused by a virus, although healthy tulips may also be variegated. Tulips are valued in beds and borders for their brilliant colours. Some smaller species, such as T. kaufmanniana and T. tarda, are suitable for a rock garden. If ingested, all parts may cause mild stomach upset, and contact with any part may aggravate skin allergies. For horticultural purposes, tulips are divided into the following groups, which are chiefly defined by their flower characteristics. This replaces the older divisions (given in brackets below.

hardiness_en: Fully hardy.

cultivation_en:

propagation_en: Sow seed of species in containers in a cold greenhouse or frame in autumn; it may take 4-7 years for flowers to be produced. Separate offsets of species and cultivars after lifting in summer, replant, and grow on.

pests_en: Bulb rots may affect tulips in poorly drained soil. Aphids spread tulip-breaking virus from Rembrandt Group tulips to other tulips. Also prone to tulip fire, slugs, and stem and bulb eelworms.
