I see the label on the fern calls it a Kangaroo Paw fern. Microsorium diversifolium.
Look on the soil at the top. See the hairy rhizome that spreads on the soil surface and sprouts leaves? Other ferns like this include 'Squirrels' foot or Rabbits' foot fern' (Davallia sp.) and 'Bears' foot fern (Polypodium aurem 'Mandianum').
This is an epiphyte, growing high in the air on the branches of a tree, or may grow on the side of a cliff where there is almost no soil. It will do well with moderate light, and is OK outdoors in the warm weather. Usually grown in a hanging pot. If you grow it in a moss basket the rhizomes may grow all the way around the basket.
Sort of looks like a Java Fern.
