Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Polystichum munitum Common Name: Giant holly fern Family: Dryopteridaceae Author: (Kaulfuss.)C.Presl. Known Hazards: Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[200].
Many ferns also contain 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[172]. Mature Height: 1 Mature Width: 0.3 Habitat: There are two distinct varieties, var munitum grows in moist coniferous woods, var imbricans grows in rock crevices and rocky soils in dry coniferous soils[60]. Forms extensive colonies[187].
Edible Uses: Root - roasted[2, 105, 118, 161]. Peeled and then baked like potatoes[213]. The roots were generally viewed by the native North American Indians mainly as a famine food for use when little else was available[256]. The roots were generally harvested in the spring, before the plant came into growth then cooked and peeled before being eaten[256].
