Collected in Taiwan by gifted plantsman Steve Doonan, this amazing Fern is hardy to at least single digits. This is a locally famous fern frustratingly slow to propagate and always red-lining the Plant Lust meter. We're happy to have some to share. Hard to imagine this is a fern with these big leathery evergreen leaves up to 18" long and with that glorious underleaf when mature. Likes good drainage and not too wet but gently moist. The Pyrossias we've seen in Arunachal Pradesh and China love to grow in moss on top of rocks and really love a good stone wall. Easy in morning sun or light shade. Mulch in winter first year or two.
