I just got a Hiawatha lilac bush and I would like to know how wide it will get. I can't seem to find any information on it. I have another lilac bush and am wondering if there is a way to make it spread a certain way.

The tree ranges from about 6-10 feet tall with a similar spread, making it suiable for use as a hedge, unless you choose to maintain its spreading growth through pruning.
There is no sure way to encourage spreading in a particular manner.
