Latin Name:  Osmunda regalis
Common Name:  Royal fern
Family:  Osmundaceae
Author:  L.

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:  2   Mature Width:  1

Habitat:  Swampy areas, fens and damp woodland[187].

Cultivation Notes: An easily grown plant[4, 187], it prefers a soil of swamp mud and loamy or fibrous peat, sand and loam[1, 4]. Succeeds in most moist soils, preferring acid conditions[200]. Requires a constant supply of water, doing well by ponds, streams etc[1]. Plants thrive in full sun so long as there is no shortage of moisture in the soil and also in shady situations beneath shrubs etc[200]. Plants are hardy to at least -20°c, they are evergreen in warm winter areas but deciduous elsewhere[200]. Members of this genus are rarely if ever troubled by browsing deer[233]. Transplants well, even when quite large[4]. Some named forms have been selected for their ornamental value[187].
