I doubt she would be like, "hey I love the house, and you're good people and all. Oh yeah i seen 3 plants in your yard, and you're going to jail. But the house is still great." this seems very unlikely. it's harder for the aveage person to rat on you once they've been in your house and have talked to you. But , indications of her personality would help us predict her actions. Did her body language change after seeing them(if she did), did she seem nervous, angry or scared at all, etc. Try to imagine you've seen something you wanted to call the cops on(rape,murder) and picture how you would react. you may even react just by imagining it ie. close arms, face becomes red, expression changes. if she was upset enough to want you arrested, nonverbal comm. would give it away. women are emotional, and its hard for them to hide their STRONG feelings. I would tie the plants down if i were you though to keep them low or move them.
