I have had some success with "easy" plants like cabomba etc. as a drop and watch but for plants like amazon sword, vallis I have had them just go limp and die on me if they are at least not getting some ferts/co2.
For the simplicity of some yeast CO2 systems (even some will add more than none) I got some decent changes with broad leafs living well and recently discovered the world of powdered fert that you mix with water yourself, about £20 for a year or mores worth, especially in a low-tech tank where your dosing is lower.
If you have minimal lighting, I also suggest that you stay away from red plants, these in my experience really need the lighting + ferts to survive in your tank.
