All ferns are shade plants and like a coolish root area, If you grow them indoors, they must be kept well shaded from ALL direct sunshine, misted with water and watered but not soaked. Cant think of any plant that will tolerate being on a window ledge with the hot sun through the glass as the glass acts like a magnifying glass and will burn the leaves, it is a bit like people sitting at a window and the heat is striking onto you, you soon feel faint and over hot, better giving sun loving indoor plants sun light but not direct onto the leaves. any ferns that I grow, all come from tiny seeds that grow onto the underside of the fronds (LEAF) so if you want to enlarge your colection, lay a frond onto a tray of compost, hold it in place with some wires bent over the frond (like a hair clip) or a few small stones down the center of the frond amd within a month/6 weeks you should see tiny little bits of growth, keep the compost moist, not wet, and mist the frond at the same time, they should be cut away when they are large enought to handle, hope this helps you with the care of your plants and the protection they need with light/sun etc if you grow indoors. good luck, WeeNel.
