Button fern

Pellaea rotundifolia | Also known as: Roundleaf Fern | Rating: 3 votes | Print / Pdf

A small, clump-forming evergreen perennial fern, pellaea rotundifolia actually looks nothing like the traditional fern – not least due to the very feature that has earned it its common name, the button fern. Its foliage comprises pairs of small, round, glossy and slightly hairy, dark green leaves, growing along thin, light brown, woody stems. A popular option for potted indoor plants, the button fern makes for an excellent rockery or woodland plant. It thrives in moist but well-drained slightly acidic soil, preferably in partial shade to protect it from hot sunlight. Tender to frost, plant in a sheltered area and mulch in winter, or simply grow under glass.
