I actually look up the species of plants specifically and sometimes its cheaper to find certain species at home depot or lowes honestly BUT make sure to was out all the soil in the potted plants before transplanting them. I actually like to use exotic angel brand plants and most of their care info on the tags it pretty similar to what they would need in a vivarium. Personally the plant species ilike to use is pothos, philodendron( the vine not the orchid), plumosa fern, traditional medium light ferns, money wart, and arrowhead. Lately ive ventured into using purple passion, silver tree, and draceana species but i cant yet tell you how easy they are to care for.
