| Species of the eastern deciduous forest are northern maidenhair, maidenhair spleenwort, and oak fern. |
|
| The spleenwort requires no insect pollinators, an effective if primitive reproductive technique. |
|
| Like the famous Ailanthus trees that grow in Brooklyn, spleenwort grows best before much soil develops between the cracks in a wall. |
|
| It is a very shaded area, permitting the growth of mosses and ferns like polypody, maidenhair spleenwort and black spleenwort. |
|
| Others are maidenhair spleenwort, two kinds of polypody, and walking fern. |
|
| Ferns, lichens and mosses are good choices for a spot with poor natural light, as are Swedish ivy, bird nest sansevieriea, and maidenhead spleenwort. |
|
| Some of them, such as crawe's sedge and green spleenwort, are rare in other Canadian provinces. |
|
| Spleenwort is one of the few vascular species typical of this habitat at the Pulliam Prairie. |
|
| The tiny Maidenhair Spleenwort, Asplenium trichomanes, not a lover of acidic soils, is an ideal candidate for dry stone walls, crevices and rocky places in the shade. |
