Polypodium subauriculatum goniophlebium ‘Knightii’ (check back in September)

Description

Synonym: Goniophlebium subauriculatum.
This is a rare fern native to Brazil. I grow it in shade and give it average moisture and fertilizer. It will grow in part sun as well. It prefers a slight acidic medium and to stay evenly moist, do not overwater. Avoid freezing temperatures. The fronds can get around 8′ long!
