Lilac
Species * Syringa emodi - Himalayan Lilac
Lilac Cultivation and usesLilacs are popular shrubs in parks and gardens throughout the temperate zone. In addition to the species listed above, several hybrids and numerous cultivars have been developed. The term French lilac is often used to refer to modern double-flowered cultivars. Lilacs flower on old wood, and produce more flowers if unpruned. If pruned, the plant responds by producing fast-growing young vegetative growth with no flowers, in an attempt to restore the removed branches; a pruned lilac often produces few or no flowers for one to five or more years, before the new growth matures sufficiently to start flowering. Unpruned lilacs flower reliably every year. Despite this, a common fallacy holds that lilacs should be pruned regularly. Lilacs generally grow better in slightly alkaline soil. Lilac bushes can be prone to powdery mildew disease, which is caused by poor air circulation. A pale purple colour is generally known as 'lilac' after the flower. The wood of lilac is close-grained, diffuse-porous, extremely hard and one of the densest in Europe. The sapwood is typically cream-colored and the heartwood has various shades of brown and purple. Lilac wood has traditionally been used for engraving, musical instruments, knife handles etc. Up to Home page

Lilacs
(Syringa) are a genus of plants, in the family Oleaceae, native to Europe
and Asia. Lilacs range in size from large shrubs to small trees, 2-10
m tall. The leaves are opposite, deciduous, and in most species simple
and heart-shaped, but pinnate in a few species (e.g. S. laciniata, S.
pinnatifolia). The flowers are produced in spring, each flower about
1 cm diameter, white, pale pink or more generally purple, with four
petals. The flowers grow in large panicles, and in several species have
a strong fragrance. Flowering starts after 80-110 growing degree days.
