The varieties of digitalis are endless! The D. purpurea types will grow just about anywhere you plant them. Full sun. rich soil. lean soil. Full shade. They grow, they bloom. More water and richer soil will give you a fuller plant with bigger flowers. I'm starting to pull them out because there are too many. I've tried to grow some of the nice D. purpurea varieties but they always cross pollinate with the wild types (which came over from England and are not native here, by the way) so I only get the true colors the year after I sow them. Here's one that came up by itself and I just love it. I am going to collect seed, but I fear that it will not come true. Lots of times you can get baby plantlets from the base of the plant, so I am hoping for that to happen.
