I have this large lilac bush and this spring it must go do to my palm habit. I was wondering if someone would be interested in it before I put the chain saw to it. I dont know the exact kind all I can say is that it has purple blooms in late spring early summer. It has been here since we bought the building and that was about 15 years ago. It is about 7 feet tall, it was taller but we keep trimming it back. I am in chicago on the sw side near midway airport.
