I’ve been covering my lilac for the last three nights with a sheet here in IN. We had the threat of possible snow flurries early this morning. Its my first year for lilac and I’m so excited. Someone from my former work gave me a snip from hers last year. It has over 6 blooms on it. I was shocked thinking it would take a least three years to bloom.
Congratulations. You must be doing something right!
