We are in the process of cutting down a overgrown 12' hedge of sorts. In its place we want to put in hedge of 6-8 4-6' tall lilacs to get to the bottom of our elevated deck. The area gets plenty of midday to evening sun.

My question is their 2 different types of dwarf lilacs so we can alternate to keep the smell for maybe 6+ weeks??? I have had a Korean Dwarf at my old house I loved that looked like a HUGE 70's Afro (I SHOULD HAVE TAKEN IT WITH ME!) after a few years.
