Well, just think about it. When you first meet her, she's all like "omg don't fite on my pretti flowers!!1 you are the ruining them! STOP IT"
Well, what if this isn't flowers? I seriously doubt it. The church is no longer in use, and I don't see a more perfect place to grow one's weed. This also explains why she tries to sell "flowers" on the street, and possibly why people talk about the glow in Cloud's eyes. After all, he did buy one of her flowers.

I'm also led to believe that the ancients in general are the street-word for "drug dealer". This would explain the frequent deaths and prosecutions.

Your thoughts?
