Cultivation

Unlike most species of ferns, the fronds of this species grow up straight and not curled inward, crozier fashion. Members of this genus are rarely if ever troubled by browsing deer.
Propagation
Spores - best surface sown as soon as they are ripe in a greenhouse and do not allow the compost to dry out. Placing the pot in a plastic bag helps to maintain a humid atmosphere which promotes germination and growth.

It is best not to try and disturb this plant.
