I have a lilac bush that my aunt gave me a long time ago. The bush is probably 10X10ft. It's at my childhood home where my brother lives. You have inspired me to go dig up some of the suckers to plant in my yard . I will wait until Fall to do so as I think it may be too late now. I'll be going for the 4 ft or taller suckers on the outskirts of the main plant. Again, thanks for sharing your knowledge and letting us all know how easy it is to grow these beautiful plants. They have been my favorite since I found them as a small child in my aunt's yard.
