When budding, the young fronds are coppery red and later green. There can also be several leaf outlets per year. The spores, which are kidney-shaped, become ripe between summer and autumn.[5]
Cultivation
Dryopteris erythrosora can tolerate a drier soil than many ferns, but is most successful in moist, humus-rich soil, with a pH range of 6.1 to 7.5, with morning or late afternoon sunshine but not during the middle of the day.[6] It is hardy zones 5 to 11. Propagation is by division in spring, separating the small crowns from the larger crowns, or by spores. It is raised as an ornamental plant in gardens because of its color change in the foliage, which change from dark red to dark green, but not very often.[7]
D erythrosora[8] and the cultivar D. erythrosora 'Brilliance'[9] have gained the Royal Horticultural Society's Award of Garden Merit.[10]
