They can climb smooth surfaces, so you'll want a tight fitting lid (with really small ventilation holes--or none at all) and you'll also probably want to smear some petroleum jelly or other barrier across the top inch or two of the walls. A lot of people do use plastic containers, especially sterilite containers with a foam gasket in the lid. Modified food storage containers, like the big cylindrical ones with screw top lids that pretzels come in, also work. Just rinse them out first.
I don't have much experience using plants in roach enclosures, but something along the lines of Sansevieria (Dracaena), Tillandsia, or Aloe species might do well, depending on how much light they get. Pothos might work as well. These aren't necessarily native to the same areas as domino roaches though. You might have more options if you keep the plants in plastic pots in the substrate. I would definitely be curious to see how it turns out if you try it.
