Outlaw mentioned Red Roses....NO, those are the typical default flower...guys pay the piper thinking those are the best.
You are doing the right thing by asking for something else.
I love Pink roses....they are much more expensive. White roses are also a breath taker. (Buy 2 dozen and have them arranged)...you'll blow her away.
I also love orchids, or anything blue purple or lavender.
I hate daisies, mums, or anything similar. (Yellow, orange, red, ......yuck)
Large fresh Tulips are always appreciated.
