A Lovely Ferner

One of our favorite ferns, known as Cat’s claw fern, is putting on quite a show this fall. Onychium japonicum is a plant I’d never met until a 1996 expedition to Yunnan, China. Although it was a bit depauperate in the wild, the potential I saw, was far exceeded by its garden performance. We now grow four different wild collections, all of which have somewhat similar growth and appearance.

We have found Onychium japonicum to thrive in everything from light shade to full sun, even in our brutal summers. The foliage is tardily deciduous, meaning it usually looks great here until early-mid January. The plant spreads via rhizomes, but the spread is not fast, so it’s easy to reign in, if your patch gets too wide. We think the incredible texture and ease of growth makes this a fern that should be in every garden where it’s growable. Hardiness Zone 7a-9b, at least.
