|all about lilacs, thanks|
|If you have a more specific question, please be sure to ask again using the Q&A form. In the meantime, here is some general information about lilacs you may find helpful. Syringa vulgaris is the common lilac, there are many different named cultivars of it such as Charles Joly described below. General information would be true for the different cultivars. I am also including information about some of the other lilacs you may find interesting as well. (You may need to cut and paste the complete url into your browser to make it work correctly.)
I hope this helps!
