This is the the same creamy white heirloom Lilac with double petals I post every year around this time. I planted it at my moms house about 20 years ago and meticulously maintained it throughout the years, the exception being the last few years. It didn’t come back as vigorously this year, probably because it overgrown. Over the summer I’ll begin thinning it out to promote basal growth and suckering, and I’ll probably give it a hard pruning this fall. It may be a few years before it will be as grand as it has been in the past, but that’s how these shrubs grow.
