We’ve been fortunate to grow a huge number of hardy garden ferns through the years, but it’s hard for any to top the amazing Pleopeltis lepidopteris, to which, we’ve given the common name, Brazilian hairy sword fern.
Below is a patch at JLBG, composed of three individual clumps, looking great, despite the ravages of summer. This sun-loving lithophytic (rock grower) also grows fine in well-drained soils. In habitat, it hails from the sandy, acidic coastal (restinga) habitats in southern Brazil (Rio Grande du Sul). Our plants came from our friends at the former Yucca Do Nursery, who made a beach front collection in Brazil in 2012. It doesn’t appear that fern had been in cultivation prior to that time.
The 18″ tall x 2″ wide, rigidly upright fronds emerge covered in thick silver hair, to which I can now relate. As the fronds age, the hair thins and the green leaf surface becomes more visible. Pleopeltis lepidopteris spreads slowly from surface rhizomes. We’ve grown this evergreen Pleopeltis in our rock garden since 2012, where it has thrived even through winter temperatures of 7 degrees F. Hardiness Zone: 7b to 9b, at least.
