Nursery contributed plant descriptions

Lilac with a slightly deeper pink eye, which turns somewhat bluer at dusk. The buds are dark, and add some good detailing to this bushy vigorous grower. Of medium height, and so it is good for planting in front of the taller phlox. Great mildew resistance, although not as floriferous as some.
