Japanese Painted Fern, another great plant for low-maintenance gardening from 'Gardening from a Hammock.' See more easy-care plants and tips for low-maintenance gardening at 'www.gardeningfromahammock.com'.
Deer fern. (Blechnum spicant). PNW native-- really a native in most parts of N. America. 8-20" tall, 3 ft wide. Partial to deep shade. Humus rich (preferably with leaf mold), moist, acidic soil. Divide in spring, sow spores in late summer. This baby thrives on neglect, so it sounds just right for me.
(July 2013 - *Pinner's Note* Ostrich Fern is edible in fiddlehead/young, coiled, sterile, frond form. See link for how to choose, handle and cook the fiddleheads. Tastes like asparagus. Excellent in pasta dishes or pickled in vinegar and oil.)
