Re: Need help with plants for my vivarium
I second Sammie's leathery-leaved plant suggestions. Along the lines of sturdy plants, I'd say you could consider:
Sansevieria sp 'mother-in-laws tongue'
Cordyline & Dracaena sp - dwarf forms
All of these plants can handle warm and lower humidity conditions (with regular watering of course). All need bright light for sturdiest (and prettiest) growth.
