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.
