The leaves of maidenhair are typically deciduous, though some varieties are semi-evergreen. They exhibit varying shapes from round to lanceolate. Leaf margins can be either entire or wavy. The leaves are generally green in color, with a smooth texture and a well-defined vein pattern. Their size ranges from 0.5 to 3 inches (1.3 to 7.6 cm) in length. These characteristics make the leaves of maidenhair identifiable and distinguishable in various species.

The flowers of maidenhair are small and simple, appearing singly or in small groups at the ends of stems, and sometimes in racemes. They exhibit a color palette ranging from white and yellow to green in various combinations. Each flower is modest in size, typically around 0.2 inches (5 mm) in diameter, with a straightforward shape. These flowers lack a strong scent and usually bloom during late spring to early summer, providing a modest visual appeal in clusters.

The stems of maidenhair are thin, wiry, and extremely tough, presenting a notable black coloration. These stems are notably resilient and flexible, which supports their survival in various environments. They typically measure about 0.1-0.2 inches (2.5-5 mm) in diameter and display a densely branching pattern, contributing to the plant's dense, tangled appearance. The stems' unique wiry texture and stark color make them a distinguishing feature crucial for identifying maidenhair.

The fruit of maidenhair is characterized by its translucent appearance, occurring in a spectrum of varied colors. These small berries, typically around 0.2 inches (5 mm) in diameter, are fleshy and bear a glossy sheen. When mature, the berries exhibit a distinctive translucency that can make their coloration particularly striking; hues may include shades of red, orange, or purple, depending on the species and ripeness. The fruit's texture is smooth to the touch, and each berry is enclosed by a thin, delicate skin which may display a slight give upon gentle pressure, indicating ripeness.
