Cyrtomium macrophyllum is looking particularly fabulous this year. This is a little-grown holly fern with a wide range from India to Southeastern China that can be found at elevations from 2,500-8,000′. The bold textured fronds arch outward to make a 2′ tall x 2′ wide clump that is semi-evergreen in most winters. It seems as if we will get good spore set this year, which may mean another offering since the last time PDN had it to share in 2003.
We live in an age where many plastic products are vilified, but every now and then, we find a reason to embrace the texture of plastic. Such was the case in 2008, when we visited The Missouri Botanic Garden. Walking through one of their greenhouse, I spotted an odd holly fern, planted in the middle of a large mass of Cyrtomium falcatum. The foliage appeared much thicker and more glossy than any of the other plants. The staff was kind enough to share a piece, which we subsequently named Cyrtomium ‘Plasticity’. We theorize it is probably a ploidy mutant with an extra set of chromosomes that would account for the extra thickness and glossiness. Here is a photo from the gardens this week, where it has become a favorite.
Arachnioides standishii is one of our favorite garden ferns. This particular collection comes from Japan’s Mt. Daisen. The common name is Upside down fern since the leaves appear to be attached inverted. Production is always challenging since spore don’t ripen until after Christmas. The foliage remains evergreen until temps drop below 10 degrees F. Hardiness is Zone 4-8.
Here’s a new photo of the evergreen Autumn fern, Dryopteris erythrosora ‘Brilliance‘ as it emerges in the woodland garden with its stunning new growth.
