Roses are the default for a reason, but they're not the only romantic flower. Peonies carry a softer, garden-party warmth. Tulips feel a little playful and modern. Orchids read as elegant and considered. A mixed bouquet built around a favorite color often means more than a dozen roses picked out of habit.
If you know their favorite flower, use it — that small detail says you were paying attention, which is the whole point of the gesture.
