About the speed: I recall the writers actually saying that professional Huntsmen and Huntresses can move insanely quickly, when they pointed out that Qrow and Winter's quick movements in their fight was intentional and not lazy animation. This doesn't mean that speed is not Ruby's Semblance. Ruby's Semblance allows her to propel herself forward at a high speed, but it does not allow her to perform the kind of quick movements that Qrow and, especially, Ozpin have displayed. Besides, Ozpin's a pretty special case considering he's most likely special himself.

About the blue "rose petals": I'm pretty sure those are not rose petals. At all. They're not the same model as Ruby's rose petals. They even have soft edges, while Ruby's rose petals have hard edges.
