'Corymbiferum'Athyrium filix-femina'Corymbiferum' varieties have crests on the tips of the pinnae and frond apex. The crests are NOT flat but are in several planes. If the apical crest gets larger than the width of frond it then becomes a 'Grandiceps'. See also 'Glomeratum' and 'Gemmatum'.Generally as for species. Will grow in most soils but prefers acid conditions; as someone says in good 'woodland duff'. Also best in light shade but will tolerate some sun in the morning and evening, or more if in damp conditions.Roger Golding / Julian Reed
'Howardii'DissectAthyrium filix-feminaHowardii & Craigii were both raised by Robert Craig in 1874. He was head gardener to Mrs. Howard at Levens Hall. They were both seedlings from a very good form of A.f.f. corymbiferum that was originally found in Guernsey. The original Craigii is long lost but this Howardii in the photographs likely to be a division from the original plant.Generally as for species. Will grow in most soils but prefers acid conditions; as someone says in good 'woodland duff'. Also best in light shade but will tolerate some sun in the morning and evening, or more if in damp conditions. Protect from strong winds which would damage the fronds.Ian Unsworth
