[It depended on the flower! For these ones, Byleth had gathered forget-me-not petals, having shredded them down into bite-sized (for them) strips of blue. They had a rather nutty taste to them.]

[He pulled out a small wad of the petals, neatly folded in on themselves, from his satchel.]

They're forget-me-not petals, and they're edible. They were easy to harvest, as these type of flowers aren't very high off the ground. I may try to find some different ones for variety, though, if we remain here for a few more days.
