She did kill Gaston in a sense. I'm guessing that eventually the rose wilted and died, and the remains of it were transported by the Dark Curse and a decaying leggless corpse appeared laying in the woods somewhere around Storybrooke because there's no magic there to keep him as a flower. Rumple could have found the body but wouldn't remember what happened so maybe Regina found the body and buried it in the woods (kinda like the way she got rid of Kurt Flynn).
