Let us be clear: there are several fern varieties that are highly toxic (such as the asparagus fern), but the Boston Fern ($33) is not one of them. Boston Ferns do require a lot of watering and don't do very well in direct sunlight, but as long as you give them the conditions they need, they make stunning additions to your home. Just make sure you check the label carefully, since many ferns do look alike!
