About

Adiantum raddianum 'Monocolor' is a tender evergreen fern that reaches a height of approximately 60 cm. It features black stems supporting triangular fronds, which are composed of rounded to triangular segments that exhibit variable lobing. The fronds start out a pale yellowish-green and deepen in color as they mature.

About the genus

Adiantum consists of ferns that may be either deciduous or evergreen, characterized by lustrous black stems. These ferns typically feature fronds that are either simple or, more commonly, divided pinnately. The individual segments can be fan-shaped, oblong, or rounded, and they produce spores beneath reflexed marginal flaps.
