Hydrangea
The first time he comes to meet to her parents he brings her mother roses and her hydrangeas.
"Hydrangeas?" her father asks loudly behead his back, "who gives a girl Hydrangea for Merlin sake? Just like his bloody father."
"Shut up Ron!" her mother tells him. "Viktor is a lovely man, I can't believe your still jealous after all this time."
But Rose disn't care at all what her father has to say because he's given her Hydrangeas. Hydrangeas, her favourite flow in the whole wide world. "How did you know?" she asks him because she knows that she's never told him there her favourites. In fact before today she's only meet him three in the twenty years she's know him. First when they were six, then at the sixteen at the Quidditch World Cup in Sweden and last week. Yes she's owled him every week or so for the last ten years but she's never told anyone that Hydrangea are her favourites.
"That there your favourites?" he asks shyly "I just do"
