Fragrant woodfern is a small circumboreal fern, the smallest Dryopteris species, usually under 25 cm tall, that grows on rocky cliffs and limestone screes. It is a wild species rarely grown in gardens, and it is best suited to cool, shady rock crevices or a shaded rock garden.
Family
Dryopteridaceae (Wood fern family)
Grows as
Fern
Light
Part shade, Shade
Water
Keep the soil or rooting medium evenly moist but well drained, and never waterlogged.
Soil
Gritty, humus-rich, well-drained mix with some lime or rock fragments, similar to its natural cliff habitat.
Temperature
Hardy in cold climates; tolerates very low winter temperatures, roughly -30 °C or colder when dormant; prefers cool summers.
How easy
Moderate
Safety
Mildly toxic: Fronds and rhizome contain thiaminase, an antinutrient that can destroy vitamin B1, and potentially cytotoxic compounds, so the plant should not be eaten raw or in quantity.
Native range
N. Finland to Russian Far East and Korea, N. & C. Japan, Subarctic America to N.
Climate
temperate
About
Dryopteris fragrans, commonly known as the fragrant woodfern, a circumboreal fern, is the smallest of the Dryopteris species. It can resemble Woodsia ilvensis in the wild, with which it shares the same habitat of rocky areas, shady cliffs, screes, and limestone talus. It typically will not reach more than 25 cm (9.8 in) in height, and accumulates dead fronds around its base.
The name refers to an appealing fruity fragrance (which some liken to primrose) that is exuded by aromatic glands found on the surface of fresh fronds. Others say that it has a spicy odor when dry. The fronds were traditionally made into a tea, as well as used as bedding by Native Americans. Like many other ferns, and members of Dryopteris in particular, however, its plant material can potentially contain an antinutrient, thiaminase, as well as potentially cytotoxic
