There is a big area along a fence in my yard in which I would like to plant 3 or 4 lilac bushes that will (hopefully) mature to be large enough to hide the 6-foot fence. I know that lilacs love the sun but this spot gets a good bit of shade from the house. There is full sun all morning but the lilac closest to the house will be in full shade shortly after noon. The lilac farthest from the house probably doesn't fall into the shade until about 3pm. I live in zone 6a.

Is there enough sun for all of them to thrive equally? Are there certain varieties of lilac that are more tolerant of some shade? I haven't yet decided whether I would like to plant multiple of the same variety or one each of a few varieties. Thoughts and suggestions would be greatly appreciated!
