I wouldn't do it. Come those hot August days they'd be toast. I keep ferns every year in a pot on my deck, gets morning sun but my 11am was in the dappled shade of an apple tree for the remainder of the day till catching just a bit of sunset. Misted and watered regularly, each year they thrived! (Had to start over every year because not enough natural light in my house to overwinter. Sad really, I've had some whonking huge ferns by summer's end that I've given away to better homes.)
