Braun's holly fern

Polystichum braunii | Also known as: Bear's bed, Shield fern | Rating: 2 votes | Print / Pdf

An evergreen fern, polystichum braunii belongs to arguably the most common genus. Its arching, dark green fronds boast broad, glossy, lance-shaped leaflets that are generally scaly on their underside. The fronds arch outward from a single point, creating a lush fan. In summer, it produces tiny, insignificant light green blossoms. Commonly called braun’s holly fern, it thrives in cool, moist sites that are partially shaded, and is naturally found as under-planting in wooded areas. It also suits rockeries, beds and borders, but requires shelter from harsh frost in winter. Mulching can be a viable solution. Pruning dead fronds quickly is also recommended.
