Adiantum peruvianum is a large, beautiful fern, native to Peru. It is of tropical origin and is quite hardy in cultivation, but requires glasshouse conditions with moderate heat in temperate climates.Adiantum peruvianum has black stems and large flat pinnules. New growth is oval shaped and displays a pale pink shade, later turning to pale green with a metallic sheen and finally to a dark green. Spores are produced around the edge of the leaflets. Adiantum peruvianum is a remarkably handsome species, the fronds spread and hang gracefully dependent as the boughs of a weeping willow. Adiantum peruvianum grows to 1m (39 inch) high x 0.8m (31 inch) wide.
Water freely in summer and keep moist in winter. While Adiantum peruvianum needs to be kept moist, do not over water the plant. This can lead to root and stem rot. On the other hand, do not let the Adiantum peruvianum dry out either. In the event it does accidentally dry out, do not be so quick to throw it away. Give it a good soaking and Adiantum peruvianum fern will eventually produce new leaves.
Shady. The plant typically grows in partial to full shade. Do not expose to any direct sunlight or even especially bright light.
Adiantum peruvianum trough not greedy, benefit from occasional feeding of standard liquid fertiliser during the growth period (during spring and through to autumn). Feed biweekly with weak liquid fertilizer during growth season.
Rich, loose, organic compost. Adiantum peruvianum prefers moist but well-draining soil amended with organic matter, much like in its natural habitat in humus-rich woods. Also grow best in slightly acidic soils. Adding lime rock to potting soil will help increase the acidity of container grown plants.
Adiantum peruvianum will do best kept above 21oC (70ºF). Do not expose to cold drafts or temperatures below 15oC (60ºF) if possible. If temperatures fall too low Adiantum peruvianum will likely go dormant, just as it would in the wild.
