I believe the rose petals are actually the visual/physical manifestation of her aura; basically a special effect byproduct. However, they have said before that semblances run in families (sort of), so it's not too far fetched to say that Summer's aura may have given off rose petals as well. Just white to go along with her white theme, or something.
