Most of the really floral hops to my nose have some grapefruit to them. Amarillo, Centennial, columbus. Citra, in spite of its name, has no grapefruit to my senses. It is all Mango sweet tea to my tastes - but very floral. Aurora is a very floral hop to me (assuming you can still find it - I haven't seen it in a while), crystal has some nice floral characteristics. I think hallertauer mittelfrüh is very floral as well, perhaps a bit herbal as well depending on what you get and/or what year you get it (I actually haven't used it in a few years.)
I'm sure others can fill in the gaps I am missing, but those are places to start.
