do hydrangeas have a fragrance
Some plants, like roses (Rosa spp.) are noted for fragrance. Hydrangea (Hydrangea spp.) is not. The most popular type, big leaf hydrangea (Hydrangea macrophylla), hardy in U.S. Department of Agriculture plant hardiness zones 6 through 9, has little fragrance, though a few cultivars may be scented.yramidal or cone-shaped flower panicles appear in late summer or early fall. They are white at first, aging to pink. All panicle hydrangeas have some scent, but varieties like Big Ben (Hydrangea paniculata Big Ben) have a more pronounced fragrance.
