Polystichum setiferum ‘Divisilobum’, known as the Alaska fern although it is a cultivar from the UK, is a finely divided evergreen that presents a lovely, low spreading horizontal rosette of soft looking foliage. The two foot fronds occasionally bear fertile bulbils that can be pinned down (best to do the entire frond) on good compost in the fall to produce a crop of babies come spring. This fern lightens the garden picture and is especially attractive en masse under somber dark evergreen shrubbery. It is hardy in Zones 6 – 8 although with proper protection it has been reported growing successfully in Zone 5.
Produced seasonally.
