Proposition: the rose petals aren't a semblance but magic.

It is heavily implied that all Silver Eyed Warriors are descended from the union of Ozma and a normal woman. If Ozmas's children with Salem were full magic users, the maybe a child from Ozma with a normal human might have some magic powers.

Alternatively, Ozpin gave Summer magic, like hedid to Raven and Qrow, and Ruby inherited it.
