I have tried hostas, they go well from Spring to mid Fall..then kaput. Fuschias, they easily get pan fried here, along with Dicentra spectabilis (bleeding heart). Coleus, is like hostas, kaput as it gets much colder, so I dropped those too. I have tried some succulents, but that corner is such poor light, so they etiolate badly, and they are just not happy there.
So far, the only plant that truly endured in my shadiest corner year round is variegated Aspidistra elatior. Just have to step up watering during the very long dry period. Just have to trim dried out leaves from time to time. It does have blooms too, but too inconsequential...grows too close to the surface, easy to miss.
