In 2014, we spotted a unique holly fern sporeling in the garden, which appeared to be a hybrid of Cyrtomium falcatum ‘Butterfieldii’, and the typical species. After watching it for several years, we christened it Cyrtomium ‘One Off’, and introduced it in 2023. In form, it’s much more compact than both parents, and has continued

When you see a catalog listing primarily these ferns together…usually an very inexpensive prices, you can be pretty much assured they were

We always love it when unexpected garden hookups yield unexpected results, and such was the case recently when, under the cover of darkness, two of our holly ferns took a liking to each other. The result of this conjugal interlude is our first hybrid of Cyrtomium fortunei x Cyrtomium falcatum, that we’ve named Cyrtomium x

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
