Aren't we a little p!ssy uh?
For near-complete, free, iguana care-info, check out Melissa Kaplan's Iguana Care website. Google it.
Her book, Iguana for Dummies, is very good. It's part of the "Dummies" series.
My personal favorite is James Hatfield's Ultimate Iguana Manual, I believe someone said a new edition is out. It's a bit more expensive than Kaplan's, but worth it. It has great plans for enclosure-building too.
I take it you live in Florida? So do I, and it's perfect for out-door enclosures nearly all-year long.
The link Adelia provided leads to numerous links, PLENTY of information if you ask me. We're not almighty know-it-alls, we provide what we know, so it's up to you to take it from there, sparing us the attitude. If all those links are still not enough for you, then you must be looking for something extraordinary, which means you will have to do your own homework.
Since you want the animal to eat the proper balanced diet, offering lots of edibles to forage on means getting a gut-ful of non-nutritional plant-matter. In addition, what's not toxic may not be so safe if consumed in large quantities, and when an iguana is hooked on something, it will engorge itself on that food item.
Good luck with your search, I'd stick to fake plants if I were you, and if there is anything else you need, let us know.
