General Description

Common male fern is a large deciduous fern native to many temperate regions of Europe, Asia and North America. The vigorous and attractive cultivar 'Undulata Robusta' has large, glossy green leaves that arise from an erect rhizome. The frond edges often have a slightly wavy appearance. With greater height, the fronds tend to become gracefully arching.

Like most ferns it excels in shade and moist soil, though once established it will tolerate some sun and drier conditions. Nearly any soil pH type is acceptable as long as there is organic matter incorporated. This cultivar performs well in woodland borders and wildflower gardens where its height and leaf texture will contrast other shade-loving plants such as hostas, rhododendrons or ground ivies. It is magnificent as a massed groundcover under tall woodland trees. It may be partially evergreen in mild winters.
