Re: Native Texas Plants
Rather than getting caught-up in state boundaries, I would design your anole viv with an eye toward the species itself. Anole's live all around the Gulf coast so you could consider plants that grow from Texas to Florida. Florida, in particular, would have species more suited to an indoor viv where temps will be warmish year-round. You could consider Microgramma ferns, resurrection fern and mosses/liverworts.
If you can provide good air circulation and even moisture (not continuously soggy but never fully dried-out) you'll have the best luck with these plants (and anole's are not rainforest species anyway).
