I live in zone 7 MD and successfully grow acaule,parviflorum,and and unidentified yellow(maybe kentuckiensis ?).They're planted out in the gardens on the east and west side of my house.East side gets a lot of shade from the trees after 11am,but the west side is practically full sun from 2-3pm on.The soil is top soil from the HD that I put in when I moved here,and remnants of the cedar or pine mulch from over the years.Watering only happens when it rains mostly.From time to time I get a little frisky after watering the vegetable garden and go around and feed everything in the flower beds.This only happens at most 3 times in a month during summer.I've lost my share of buds to the local wildlife over the years,either squirrels or rabbits.This year I was prepared for them with poison blocks and a pellet gun.LOL!
