Perennials
Woodwardia unigemmata
Jeweled Chain Fern
Woodwardia unigemmata is an evergreen fern with long, arching, finely divided fronds. New fronds emerge a rich red, age through rusty tones, and finally mature to glossy green. The fronds can grow to impressive length and often drape over banks, rocks, or the edges of shaded borders, giving a lush, cascading presence in woodland or moist garden settings.
Native to moist, mountainous regions of Asia, Woodwardia unigemmata is adapted to high rainfall and shelter.

Design tip
Foliage and form do most of the work here, so lean on texture and repetition rather than one flowering moment. Keep it out of hot afternoon sun and layer it with woodland companions for a full, settled look.
Where to see it
This plant can be seen at the Heronswood.
