these are the rules with flowers:
1. flowers are for girls
2. girls say "you dont need an excuse to get me flowers. you can get me some anytime."
3. if you are thinking about getting them, i dont see it ever hurting.

 

flowers are always a nice gesture, just never get a black one.

Send a thinking of you card to her, send the flowers to her mom.

 

^ This. I think it's a good bet that you sending flowers to this person's sick mother would mean more to them than any gift you would give the person directly.
