I have a large section of yard that is filled with the old fashion lilacs. This past year we did a total rejuvenation and cut them all down to about 6 inches. Extreme and scary but they needed it badly. Anyway, I was thinking about widening or elongating this section of lilacs with more lilacs and I was curious about other varieties. I know very little about other kinds and just wanted some advice on whether there are certain varieties that would go better with my old fashion lilacs. I thought about just adding the white form of old fashion lilacs - not very creative I know. I wasn't sure if I should get some that bloom at different times. Also, I felt that maybe they should all have the same mature size - not sure. Anyone have pictures of mixed varieties together?
