Your knowledge, your growing conditions and of course your photos. I love ferns and I grow a few Ferns as houseplants but there are a couple of different types of natives that are growing in my yard too.
These are a few that I grow in containers on my back porch.
Blue Star Fern (Polypodium aureum) Microsorum diversifolium (Kangaroo Paw Fern)
Microsorum punctatum (Elkhorn Fern) Neottopteris nidus (Birdsnest Fern)
