We humans do grow ornamental plants indoors in pots and they still do most of the things their nature requires without ever feeling the breeze or being visited by an insect. I think the best case would be that the sunless plants would be like pet cats who were raised from kittenhood indoors and never allowed outside even for a moment. I have known such cats, and if they have a lot of human love and maybe the company of another cat, they grow used to their condition and come to be fearful of the outdoors, but in my opinion these confined cats are missing some of their essential catness. This is a controversial opinion--where I live, none of the private adoption organizations will allow someone to adopt a cat or kitten unless they promise never to allow it outside.
