I'm no expert but the one she's holding looks like a white clover which means in the language of flower " think of me ". The one tied to her wrist looks like an anemone which can mean (amongst other meanigns) the death of a loved one. It can also symoblize death in eastern countries like Japan where white is the color of funerals.
I may be wrong though, but this is what i got after some quick google research.
Thing is, I did a google search last night too, and I got completely different results. I didn't want to post them lest that skew the findings. My Google-Fu identified the one on her wrist as a Gardenia Brighamii, which means "secret love". But then again, neither the Anemone nor the Gardenia have 7 petals.
I think we might need someone with some actual knowledge here.
