24 May 2018 Lilac Bushes. Posted on May 24, 2018 by Durgan 24 May 2018 Lilac Bushes.24 May 2018 Lilac Bushes. Two lilac bushes one white and the other purple. Absolutely pristine. The Sun is setting so they have a slight change in color. Their odor is divine. Some miserable winters were hard on them, but after several years they are coming into their own.
