About:

A rare and endangered fern species that can be found in the swampy coastal areas of the far north, as well as in the thermal regions of the central North Island. Unfortunately, both of these habitats are currently under significant threat due to factors such as drainage activities or ongoing geothermal development. This particular fern is deciduous and displays attractive fronds that can grow anywhere from 30 to 90 cm in length. The fronds feature narrow, pointed, light green leathery leaflets that possess finely toothed edges, adding to their visual appeal. It is important to note that this fern is frost tender, and therefore, it should ideally be planted in a consistently moist site. This resilient plant can thrive in either open areas or shaded environments, which allows for some versatility in its growing conditions.
