What is one of the smalest growing lilacs i can plant is maryland? How big do they get? What methiods are used in taking can of them? Will they do alright in full sun for the first couple years then partial shade later? I have to incorparate them into a bed that is out in the middle of the yard with full sun. but this bed has a cherry tree there now and she wants a magniloa planted when i put in the lilacs and azleas . Any input is great ,thanks.
