Could I plant some flowers in my oriental fire bellied toad tank?

I am going to plant them from seed.


I was thinking johnny jump ups or marigolds.


I would like to know plants that do well (I'm looking for plants that are easy to grow from seed)


Any plants that I cannot use?

The only thing I can think of would be hibiscus, but it's pretty hard to keep alive in a terrarium. i would not suggest marigolds because they can be poisonous - I'm not sure about the other ones.
