Pretty ones, woofie! Let us know next spring if they survive, we'll be pullin for 'em.
Hm, Lin that little fern in my first picture has a distinctive feature that I don't see on the Swamp Fern, its terminal leaflet is nearly twice as long as the others. As to the weedy ones, they sure may be the Nephrolepsis cordifolia, but they never seem to get quite as large, staying under about a foot, so that's why I thought they were Boston ferns. Either one is a pain in the patootie.
