Carolyn,
A lot of the varieties that I have are very fragrant. They seem to smell the strongest on day 1 and 2. The two varieties that instantly come to mind are "Albert Greenberg" and "King of Siam." You don't even need to be by the flowers to smell them. I can't think of any that I have that have no smell at all.
Because i have so many plants, when i get a massive bloom and a nice breeze, the whole yard smells like them!
