This Lilac came from a box store clearance wrack, and was labeled "old fashioned Lilac", but I could tell right off that it wasn't your typical vulgaris. The leaves are quite a bit smaller than vulgaris, and so are the stems. The stems are twiggy, and it doesn't seem prone to sucker. It produces blooms not only were the stems terminate, but from side buds as well. It's not prone to mildew either. The bloom panicles aren't as big as vulgaris types, but the individual blooms are larger. It has a light, sweet fragrance, but it's not the typical Lilac fragrance. Any idea what it is?
