There are a few ferns in a bed on the north side of my house inherited from the previous owners. I neglected them last year. Because they looked so good, I thought they were "low maintenance". I'd like to give them a bit more attention this year. Can you help me identify this fern? Is it an "Autumn Fern"? It is low-growing (about 18" from ground to tip) and about 10" wide at the widest point. Many of the leaves have had an orange-hue through the winter, but it wasn't as pronounced as some photos I've seen of Autumn Fern on the web.
