If all else fails and you can't find them locally, we had these edible rosebuds, and these edible rose petals delivered same-day with Amazon. Easy as that. You'll definitely have leftover rose if you go this route. There are a million ways to use them: in tea or hot chocolate, in desserts, or as an herbal soak with Epsom salt. The sky is the limit here!
