Well, my oldest rose I have is a Mardi Gras.
Rose (Rosa 'Mardi Gras')
I planted that rose in 2008 when I had less than no clue. It's a wonderful rose, almost constantly in bloom once mine gets going, survives my winters with no problems, etc. But if you're looking for scent, Mardi Gras doesn't have much of one. You may want to try a Mr. Lincoln then. Can't go wrong with Mr. Lincoln.
Hybrid Tea Rose (Rosa 'Mister Lincoln')
Actually, Mr. Lincoln, Oklahoma, Olympiad.. those 3, to me, are almost interchangeable as they look & smell almost identical. But Mr. Lincoln has larger blooms that purple as they age and Olympiad are more of a clearer, hotter red.
Rose (Rosa 'Olympiad')
Rose (Rosa 'Oklahoma')
Pure Perfume is a great scented white.
Rose (Rosa 'Pure Perfume')
Golden Masterpiece is a magnificent yellow.
Rose (Rosa 'Golden Masterpiece')
And, of course, my absolute favorite, BlueGirl
Rose (Rosa 'Koelner Karneval')
All of these roses are tried & true in my garden.. so if I can grow them, anyone can grow them!
