I think I read that the fantasy are unstable which means they change, I don't remember reading anything about how to get one to fantasy more, it's their make up and once that changes, you can't do much about it.

I hope someone has a better answer. tish

You might try growing it cooler, on the bottom shelf.

Misting might also help. A change of humidity could add deeper color to some plants. Maybe it will make spots on these--and maybe you won't want water spots on your flowers!
