Wikipedia Abstract

Dryopteris dilatata, the broad buckler-fern, is a robust species of deciduous or semievergreen fern in the family Dryopteridaceae, native to Europe, particularly western and central Europe. In southern Europe, it is mostly found in mountainous regions. It is also found between the Black Sea and the Caspian Sea. It grows to 90 cm (35 in) tall by 120 cm (47 in) wide, with dark green tripinnate fronds, the ribs covered in brown scales. The species and the cultivar 'Crispa Whiteside' have both gained the Royal Horticultural Society's Award of Garden Merit.

Attributes

Allergen Potential [1]  Medium
Edible [2]  May be edible. See the Plants For A Future link below for details.
Hazards [2]  Although we have found no reports for this species, a number of ferns contain carcinogens so some caution is advisable; The fresh plant contains thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase; However, there have been reports for other species of ferns suggesting that even cooked fronds can have a long term harmful effect. Some caution is therefore advised.
Lifespan [2]  Perennial
Structure [2]  Fern
Usage [2]  An infusion of the leaves has been used as a hair wash;
Height [2]  16 inches (0.4 m)
Width [2]  20 inches (0.5 m)
Light Preference [3]  Mixed Sun/Shade
Soil Acidity [3]  Mostly Acid
Soil Fertility [3]  Intermediate
Soil Moisture [3]  Moist
