Some ferns have been on earth for more than 300 million years and are found all over the world (about 12000 species).  They have a primitive but complex reproductive system.
Today they are popular as indoor plants, in courtyards and they soften the landscape in the garden.                                                               Outdoors they should be planted on the south side of the house in cooler shady areas.  Keep moist but do not over water.
Indoors, particularly with air conditioning systems, place pots on a tray filled with gravel and water to prevent drying out.  Occasionally spray the foliage with a fine mist of water.

Avoid strong light.
