The tight, compact habit of Cityline Paris hydrangea makes it a well-behaved garden or landscape plant, while its vivid deep red flowers make a bold and stylish statement. One of the smallest hydrangeas on the market, it does not need pruning (in fact, don’t prune it at all!) and its deep green mildew-resistant foliage looks handsome all season. Cityline Paris keeps its red color in most any soil, developing only purplish centers in acidic soils.
