While roses are pretty to look at and sweet to smell, they also can be delicious to taste.
Rose petals are indeed edible, but you should only eat them if they have not been sprayed with anything nasty (pesticides and such) so do not use roses from a florist because they have almost certainly been sprayed with chemicals (and anyway, most commercially grown roses aren't very aromatic). Just use and depend on Herbies Rose Petals.
Used in many Middle Eastern and Indian cuisines, roses make sweet, floral preserves and vibrant garnishes.
Rose petals are added to Moroccan and Middle Eastern dishes for color and flavor and are equally popular in savory and sweet recipes.
Add 1 part rose petals to 6 parts of Ras el Hanout to make it even more exotic.
