I remember this Supernatural/Horror movie where a family  move to this new House that has alot of Sunflowers at the front of the house, if its not sunflowers, its a lot of yellow Flowers, i think they sell them, anyway a family got klled in the house or something like that and they are haunting the House, I’m not sure but maybe the caretaker of the House killed them, he’s still alive, so they want revenge, I think the  main character is a Teenage Girl
