About:

This fern features fronds that can grow up to an height of 1m tall. The fine pinnate leaflets exhibit a growth pattern that is less drooping compared to S. cunninghamii, presenting a more distinct appearance that is reminiscent of a fan. This unique fern is typically found in localised regions of the upper North Island, as well as on Great Barrier Island and Great Mercury Island. It thrives in rich, damp soil conditions, ideally in light shade, and tends to prefer warmer environments. However, it is worth noting that this fern is extremely challenging to establish successfully in a garden setting.

Natural habitat:
Coastal to lowland. In the North Island usually associated with kauri (Agathis australis) forest, and/or regenerating forest and scrub nearby established kauri forest remnants. It also grows along steep sided streams and on rocks within gorges.

Growing environment:

Shade, Wetland, Wind & Coastal tolerant.

How to grow:

Can be grown from rooted pieces and fresh spores. However, spores can be very tricky to raise and plants resent root disturbance. Nevertheless, once established this species is one of the few members of the New Zealand Gleicheniaceae that is easily maintained in cultivation.
