Answer: Polystichum setiferum (P. angulare) might handle some direct morning sun (the earlier in the day the better) and does fine in bright dappled light all day. The more light it receives the damper the soil should be, otherwise the foliage will dry out and turn crispy. On the other hand, this fern needs a well drained soil meaning not sopping wet or saturated, especially in the winter, or it will basically rot. (In deeper shade it tolerates a fairly dry soil compared to some ferns.) All of which is to day, it would not handle noontime or afternoon sun and I would be cautions with late morning sun as well. This lighting guideline is true for any fern I can think of. I hope this helps.
