what a super sweet idea laurie!
First off ,I have to admit I am a non-flower person. I am too frugal (cheap!! LOL) to spend money on something that is going to die. I would do a real plant over flowers.
The other idea I have is something that i did a long time ago. G and i went away for our 10th anniversary. I arranged to have bottle of champagne and a cheese and fruit tray sent to our room. we were able to sit ut on our balcony, watch the ocean and drink champagne together.
Since I know you are going with the flower theme as a way to say TY for your flowers (love that you 2 are still romantic!!) maybe just have a single rose sent to him with either the strawberries or champagne deal?
