Nan's Blossom Shop! We have been Nita's people for decades but the new owners of Nan's hit it out of the park for us recently. Paul oversaw all of our arrangements and they were lovely.
I've always had good luck with Aggieland Flowers and Chocolates. My mom used to be a florist. She would always go check out the local florists in town when I was a student here. That was her favorite.
