I have been trying to get my mom to plant interesting and native plants from our area in her garden. Mostly I received a plain no from her but, I have received a yes about a queens lady slipper. I have read the basic care for them on a few places. I live in South eastern Massachusetts. I have heard these plants were quite common when my mom was young but, I have never seen a single one in person. The only wild plant I know of is in my cousin's aunts house that lives in central New Hampshire and I rarely visit them. I am hoping you might be of help choosing a good soil mix and spot in my yard that would be most likely to hold long term success. I have a spot in my back yard that is shaded by a few large maples and is moist and cool to the touch. The spot is on the north side of my yard and gets only a few hours of direct early morning sun then is shaded by the trees the rest of the day. The area is also raised about 6 inches from the rest of the yard. I believe this may be the best spot though I have no idea if the soil in neutral or not. I believe my soil is already naturally acidic in nature and any mix I plant will also become acidic over time due to the rain. Would this spot be good or should I look for a different spot and should I use the soil there replace the area where the Cypripedium will be planted?
I also have another question. Is Cypripedium reginae the only species that is native and if not what species also live here? I would like to get a few species planted if so.
edit: I meant to say "this coming spring" not "this spring" in the title.
