Plants that can live in shallow, poor soil?

[chelsea716]

So I am making my first REAL terrarium, no animals just plants. I have made small ones with things from succulents to flowers to mosses. I have a few plants I was given to work with, and i have some money to spend on buying some. I have done venus fly traps in terrariums and they have thrived, I have also have pothos thrive in the same conditions as the venus fly trap. I have a small layer of pebbles for drainage and then a mix of a sorta clay-ish dirt, some coconut fiber from a old hermit crab tank clean out and some pearlite in their. Its a good mix for the venus fly traps (or so I have found ober the years), and I want to add more plants to my terrarium. I have ABOUT 3-4 inches of this mix with a inch or so of pebbles. Its a 10 gallon tank, 20x12x10 I think... or 20x10x12. I have a mesh lid for now but I am getting a proper lid (aquarium or terrarium hood for lights). Something short and hardy is good. I have quite a bit of space and the venus is thriving so far after about 2 weeks. I have sorta a "Dr. Who" theme, so something alien like is nice. I am going to be keeping the tank rather cool in the winter and warmer in the summer like the venus needs. Any ideas? I am going to add moss soon.. I hope. Maybe frog moss or something I can find outside.

Any help? I have lots of pothos, the venus and a few air plants so far, any other ideas?
