Dainty fern whose fronds form rosettes on cliffs and boulders

Asplenium trichomanes maidenhair spleenwort

Plant grows in the wild/spontaneouslyPlant is native to PA

Overwintering perennial fern that grows in dense rosettes on cliffs and boulders.  The species name 'trichomanes' comes from Greek 'tangled mass of hair' referring to the tangle of dark stems that go together with the floret.

The trailing sterile fronds emerge first, then fertile fronds come in a bit later and are more erect.  This fern is the easiest of all Spleenworts to grow in a garden.

Usually grows on limestone or non-calcerous rocks, prefers rock crevices.  Prefers neutral to moderately acidic soil.

Range is from Nova Scotia to Minnesota, PA, and south to Louisiana, Mississippi, Texas, and northern California.
