Sorathein I have a book on terrariums and it said you can put in..
Minature begonia's
Dwarf
rose-stripe earthstar
false aralia
minature african violets
tri-color variegated strawberry begonia, there are many moisture lovin
plants that one would not think would work but I guess they do! with the right soil mixture and conditions. it also said the acid level would make or break an terrarium to use hardwood charcoal on top of drainage material as it will absorb the acids produced by
plants and soil bacteria,< for a closed terrarium
For an open one the acids are ordinarilly flushed away as excess water drains from pot
