it is illegal to transport it IN FL or TO FL?
This stuff is abundant in FL, as it is invasive. I would think the OP could find plenty in an area nearby already in the state. If it is being contained in a home garden and not allowed into a public/natural waterway I see no harm in it, except that perhaps the seeds are transported by birds. But really, I have been to FL and seen this stuff, it isn't going anywhere -unfortunately it is in FL to stay, very strongly I am afraid. Maybe the pond area could be fenced or netted to keep birds from the seeds, or the flowers could be snipped off before the seed is viable. I would also research other plants that offer the benefits you need without the invasive properties. I am sure there are others. I grew hostas and hibiscus once in a pond, and they grew fine, don't know if they are edible for your bunnies though.
