I recently was given a lilac sucker from a bush at a farm in Illinois. I don't know what kind it is, just your basic old farm lilac. I've potted it and it is sprouting leaves now.

My question is, where to put it? I have a good spot for large bush, but it does get all day sun, and my back yard (south of the house) tends to run hot (especially this year). Would that be a particularly bad place? It would be next to a forsythia and a flowering quince, which are doing reasonably well, but I should say that this bed is less than one year old, so they are just starting out as well.

I understand that lilacs need water, and I do irrigate, so that should not be a problem.
