Athyrium filix-femina Rotstiel - Lady Fern

Athyrium filix-femina 'Rotstiel' is a form of lady fern with a compact habit, and with beautiful red stems that enhance its elegant light green foliage. A plant that thrives in moisture and shade, it is very hardy and resistant to powdery mildew. Perfect for shady gardens, the edges of natural ponds or cool woodlands. This cultivar is also suitable for container cultivation near the house, to fully enjoy its beautiful colours.

The lady fern, known as Athyrium filix-femina in latin, belongs to the family of Athyriaceae. It is a perennial plant native to all temperate regions of the Northern Hemisphere. Athyrium filix-femina 'Rotstiel' has relatively slow growth. This fern establishes itself permanently through its creeping rhizomes if the conditions are right. It reaches a height of 60 cm (24in) with a spread of 80 cm (32in), and eventually forms large clumps from a central point. The bipinnate foliage is deciduous and is a bright light green colour. The undersides of the fronds are covered in orange spores. The stems emerge bright red, becoming darker red over the months. However, their colour is less intense than that of the 'Lady in Red' cultivar.

Plant Athyrium filix-femina 'Rotstiel' in humus-rich, cool, neutral to slightly acidic soil. This perennial thrives in shade or partially shaded areas with morning sun, under trees or shrubs with which it can compete. The foliage slowly dries out from November, but cutting it should be avoided before the end of March as it protects the stump well. During the first year of cultivation, it is necessary to ensure the watering of the young plant to help its establishment. Athyrium filix-femina is primarily a plant for damp shade or partial shade, reaching its full potential in woodlands or around water features that reflect its elegant silhouette. It is ideally associated with conifers, fuchsias, and hydrangeas. It also adapts well to cultivation in large pots in the shade, allowing for a closer appreciation of its airy and graceful foliage. This cultivar also pairs well with perennial plants with purple foliage, such as the Heuchera 'Purple Petticoats'.

Good to know: A favourite of Victorian ferneries in the late 19th century, Athyrium filix-femina has provided numerous horticultural varieties with variegated fronds or curious shapes, including the variety 'Victoriae' or 'Frizelliae'.
