I would suggest that a majority of the consensually great perfumes for men have florals in them. In classic compositions they are necessary to balance off the pungency of dry herbs or leather notes or build bridges to sweet spice or wood notes. Herbals without floral notes easily become acrid.
Anyway, I can second or third (etc.) many of those named:
C&S No. 88 (dominant rose) & Cuba (background rose, but important), Neroli
Pehaligon's Hamma Bouquet (rose, jasmin)
Patou pour homme (geranium, jasmin)
Dukes of Pall Mall Cotswold (white florals)
AdP Colonia (rose, ylang)
Knize Ten (geranium, rose, orris)
R de Capucci (rose, jasmin)
TDC Bois d'Iris...
I could go on forever, really
