Lilac tree Syringa (Lilac) is a genus of about 20–25 species of flowering woody plants in the olive family (Oleaceae), native to woodland and scrub from southeastern Europe to eastern Asia, and widely and commonly cultivated in temperate areas elsewhere. The genus is most closely related to Ligustrum (privet), classified with it in Oleaceae tribus Oleeae subtribus Ligustrinae. Lilacs are used as food plants by the larvae of some Lepidoptera species including Copper Underwing, Scalloped Oak and Svensson's Copper Underwing and Saras.
Etymology Via Arabic lilak from Persian nilak meaning "bluish", ultimately from Sanskrit nila, which means "dark blue". The genus name Syringa is derived from Greek syrinx, meaning a hollow tube or pipe, and refers to the broad pith in the shoots in some species, easily hollowed out since ancient times to make reed pipes and flutes. The English common name "lilac" is from the French lilac ("shrub of genus Syringa with mauve flowers"), from Spanish lilac, from Arabic lilak, from Persian lilak, variant of nilak "bluish", from nil, "indigo", A pale purple colour is generally known as lilac after the characteristic color of the flowers of many kinds of lilac, especially Syringa vulgaris.
Symbolism Lilacs are often considered to symbolize love (see language of flowers). In Greece, Lebanon, and Cyprus, the lilac is strongly associated with Easter time because it flowers around that time; it is consequently called paschalia. Syringa vulgaris is the state flower of New Hampshire, because it "is symbolic of that hardy character of the men and women of the Granite State" (New Hampshire Revised Statute Annotated (RSA) 3:5). "When Lilacs Last in the Dooryard Bloom'd" is a poem written by Walt Whitman as an elegy to Abraham Lincoln. The poem was set to music by both Paul Hindemith and Roger Sessions. "Syringa" is the title of a poem by John Ashbery, from his collection Houseboat Days. "Lilac Wine" is a song written by James Sheldon in 1950.
Description They are small trees, ranging in size from 2 to 10 metres (6 ft 7 in to 32 ft 10 in) tall, with stems up to 20 to 30 centimetres (7.9 to 12 in) diameter. The leaves are opposite (occasionally in whorls of three) in arrangement, and their shape is simple and heart-shaped to broad lanceolate in most species, but pinnate in a few species (e.g. S. protolaciniata, S. pinnatifolia
Cultivation and uses Lilacs are popular shrubs in parks and gardens throughout the temperate zone, and several hybrids and numerous cultivars have been developed. The term French lilac is often used to refer to modern double-flowered cultivars, thanks to the work of prolific breeder Victor Lemoine The wood of lilac is close-grained, diffuse-porous, extremely hard and one of the densest in Europe. The sapwood is typically cream-coloured and the heartwood has various shades of brown and purpleto split into narrow sticks.
Species Syringa komarowii is a species of lilac native to central China, commonly called Nodding Lilac.It is a shrub growing to 3-6 m tall, with erect branches. The leaves are oval-oblong, 5- 19 cm long and 2-7 cm broad. The flowers are fragrant and range in colour from pink to mauve, sometimes with a white base; they are produced in early summer on panicles 4-25 cm long and are attractive to bees, butterflies, and birds. The panicles often hang limply, which is how the plant got its common name; the clusters look as though they are nodding. Syringa reticulata (Japanese Tree Lilac); Chinese:bao ma ding xiang; Japanese: hashidoi is a species of Lilac, native to eastern Asia, in northern Japan(mainly Hokkaidō), northern China, Korea, and far southeastern Russia.It is a deciduous small tree growing to a height of 12 m. Syringa × persica, the Persian lilac, is a hybrid between Syringa laciniata and S. afghanica. Its height grows up to 4-8 and spreads about 5–10 ft, and prefers warmer winter climates (Zones 5-9) than many species of lilac.
