Hi all, This is the happiest fern in my shady yard & I'd like to know what sort it is so I can get more! I *think* it's some kind of holly fern, but I'm not sure. It's very deep green, evergreen over the Vancouver winter, bunching, and new fronds emerge a reddish-purple, and the pinnae each roll out individually. It is very leathery and shiny. It's far thicker & heartier than the 'Dryopteris erythrosora' I have elsewhere in my yard. Thanks very much for your help!
