Varieties
The lilac’s botanical moniker is syringa vulgaris which makes it a sibling to the olive tree. Amongst this group are 20 more strong types of plants such as privates and jasmines. Within these types are hundreds of additional species. The lilac itself boasts over 1,000 species.
Bloom
Not all of these variations are similar as some grow in a bush formation, some grow in trees and some bloom at unusual times within the year. These multiple variants and colors are all of different origins and acclimatized to different conditions. The Souvenir de Louis Spaeth blooms most beautifully in pink and the Japanese variant can grow to an astounding 30 feet.
