I had the same thing happen. I live at 1200' elevation, so our spring is behind those down in the valley. You have it right, it was the weather than confused the poor things. Last year we had great blooms. 2 years before that we had a killer frost on May 14 and the following year, 5 inches of snow on May 14! It's a wonder I see the lilacs bloom at all!

Thanks, Herbalbetty. I feel glad it's not something I did! Will look forward to next spring's lilacs. Funny, my pinxter did great!

It happened to mine also. I am pretty sure it was that late frost that did mine in. They all bloomed, but seemed to be half the size than normal. I haven't really done much to mine since I planted them, so this year I will be putting wood ashes on them and fertilizing them to give them a good start for next year.

Me too. There's always next year.
