About this genus:
Athyrium (Lady ferns) have long been valued (case in point: the Victorian fern craze) for being an easy-to-grow and spectacular looking genus of, tough, deciduous, garden ferns. Although the Japanese painted fern, Athyrium niponicum, was only used in the garden relatively recently it is now the most popular species.
The sheer volume of named cultivars of Athyrium for sale is incredible. Despite the popularity of the genus Athyrium most gardeners have never grown more than a fraction of the 80-plus species
As mentioned, Athyrium niponicum is also extremely popular and was selected as the 2004 Perennial Plant of the Year. Many wonderful cultivars are around because of the diversity of the foliage colour.
As you can imagine by their popularity, most members of the genus Athyrium are quite easy to grow in a wide variety of garden conditions. Despite a reputation as shade-only plants many Athyrium will do well in sun as long as there is enough moisture to stop them drying out (think: they are often grown and displayed in hot, humid, sunny, glass houses aren't they!!!?)
