This spring I planted some fragrant roses for the first time to replace my barely fragrant Knock Out Roses. The first to just fully bloom were the hybrid white rugosas Blanc Double de Coubert and White Pavement. However, these roses seem to have no fragrance for me so far. I have to stick my nose right into the flower and then I get the barest hint of a fragrance (I almost stuck my nose right into a busy bee!), and even then it just smells more like leaves than flowers.

Do I have to wait for later in the summer or even until these roses are older before I get fragrance from these? They seem fairly vigorous.

Thanks!
