I can never get used to how early they bloom here. In SD where I grew up it was late April or May. One year I missed them blooming and I was so bummed! Lilacs realy don't do as well in the South. When we moved in this house there were 2 almost dead bushes. I dug the grass away from their roots and Miracle Growed them for a few months. The next summer they took off! They still aren't as spectacular as up north but beggars can't be choosers. They..smell..heavenly!
This little guy thought so too..not sure what breed he is. In my hometown, in the park they had rows and rows of lilac bushes..they were huge. When we lived in Fargo, the bushes in the backyard were 12-15 feet tall. You has to climb on the roof of the garage to get the big blooms on the top!
