I have two types, Adiantum jordanii, native to California, and Adiantum pedatum, not native but there's lots of them growing everywhere.
Both are part of the greenhouse weed fern collection which includes Squirrels Foot Fern, Boston Fern, Mother Fern, Holly Fern and most recently, a Staghorn Fern...plus a few I haven't identified yet.
There used to be a bronze colored Maiden Hair advertised. I really wanted one of those but never found one. Now, I can't even find a photo on the interweb.
