We can grow lilacs very well here in snowy Utah. Lilacs need the winter cold to grow properly and well. I got very excited about the blooms on this one. My neighbor has a lovely deep purple lilac by our fence that would have gone beautifully with this on our side. Until I read about how it suckers abundantly. Neither of us need to deal with that and I've read elsewhere how this one does that. Which is too bad because it really is a beauty.
