Terrestrials for pennsylvania growing?

[Call_Me_Bob]

Hi guys. so i have a spot where id like to start a bed of terrestrial orchids. i need your help to tell me if there is anything that would be able to grow in the area.

the bed would be right up against the house, not sure how the soil is, but i can replace it.

like i said, up against the house and on the northwest side. there are two tall tall trees in the backyard so the bed would probably be in bright shade most of the day.

any idea of plants that would be happy here? Id like something that i can leave in the ground all year.
