P. virginianum is hardy to Z2.

This is a beautiful small evergreen fern. I see it fairly often in the wild around here, growing on boulders and climbing exposed rock faces. I've only tried growing it in the garden once, and failed. It's said to be tricky to get started, and you need just the right soil and conditions---It's said that the soil needs to be high in organic matter but low in nutrients. Once established, it clearly can take care of itself.

According to the Missouri Botanical Garden:

Native to temperate climates of the Northern Hemisphere. I've only seen the few planted at the base of trees and rocks at Jenkins Arboretum near Berwyn, Pennsylvania, that are labeled. The soil at that site is moderately acid and a good quality clay or silty-clay loam. Most references say it can grow in acid or neutral or alkaline soils that are well-drained, being dry or moist. They grow on logs, ledges, cliffs, and other places. They look pretty, and they have the simple pinnate leaves that are not double or bipinnate like the "typical" fern.They have evergreen foliage, as I took photos of the still green fronds in March. The rhizome roots are supposed to be edible with lots of sugars inside and they can be used for medicinal purposes. I have not seen this plant offered in regular garden... read more
