Overview
Pellaea atropurpurea is a fern in the genus Pellaea, part of the Pteridaceae family. Pellaea atropurpurea grows best in partial shade and shade, and tolerates rocky and well-drained soils. Suggested uses include rock gardens, crevices and shade gardens. It is native to Ontario and Quebec.
In the garden
Pellaea atropurpurea is a fern native to Ontario and Quebec that favours rocky, well-drained places. In cultivation it is most often used where soil is shallow or stony; its growth period is concentrated in spring and summer when the fronds are produced. Use the species where a fern will need to occupy tight spaces rather than open beds. Give Pellaea atropurpurea partial shade or shade and a sheltered aspect away from strong prevailing winds. It prefers rocky, free-draining substrate with dry to medium soil moisture — avoid clay or waterlogged hollows. Position the crown to sit in a crevice or on a ledge so roots can find pockets of soil; mulch lightly with grit or leaf mould to maintain a drier surface while retaining minimal moisture around the root zone. In a UK garden it suits rock gardens, stone walls, ledges and shaded crevices in borders. Group with other shade-tolerant rock plants where drainage is assured. The fern’s seasonal fronding in spring and summer makes it particularly effective in narrow stone gaps where broader perennials cannot establish.
