Plant Biography

Native to New Zealand where it grows in cold and wet alpine conditions, hence its Latin and common names which both refer to mountains.

It is one of only few New Zealand ferns that can survive above the mountain tree line, which throws some light on its distinctively ancient character.

In cultivation, Mount Kiokio is frequently used by gardeners to create ground cover in shaded borders of the garden.

Care & Size Guidance

Care & Size Guidance

Blechnum montanum thrives best planted at a site with very moist and rich soil, situated in part shade.

Whilst it dislikes drought and humidity, once it has been established it is more tolerant than you might expect.

That said, it is only borderline hardy for the winter weather in the UK, so it’s best placed in a sheltered spot and may need to be provided protection during colder frosts.
