Common Lilac (Syringa Vulgaris)
Common lilac is a small tree about 7m (23 ft) high with lilac-coloured. Lilacs have been cultivated in the gardens of the Orient for centuries but the common lilac was first introduced into Europe (Vienna) in 1566. From Vienna it spread throughout the Continent, arriving in Great Britain in 1597. In the wanner regions of southern Europe it has become fully naturalized. The same is true of the Persian liliac, Syringa persica, which has also been grown in gardens for generations. Last of the lilacs to become naturalized in Europe is the Hungarian lilac, Syringa josikaea, named after the Baroness Josika of Hungary who discovered it in the mid-19th century in a garden in Marmarosh. The common lilac and other botanical species can be propagated readily by means of seeds sown in the autumn, directly after harvesting.
To ensure lengthy and abundant flowering lilacs should be given an occasional application of feed and thinned out regularly by removing weak branches with poorly developed terminal buds and old wood; this, of course, should be done successively so as not to remove too many flower buds at one time. Old, faded flowers should also be removed, not only because they are unattractive but also to prevent the plant from becoming weakened by the production of seeds.
