The maidenhair spleenwort usually grows on limestone but may also sometimes be found on other rocks. It is found mostly in the upper northeast, seldom being seen south of the Mason-Dixon line except for some parts of the Appalachian Mountains.
This plant forms a delicate rosette of pinnate fronds, the pinnae being almost round and toothed on the top and outer edge.
Of all the rock spleenworts native to northeastern North America, this is the easiest to grow (except, of course, for the ebony spleenwort, A. platyneuron, which grows on rock as well as in soil).
