Botanical name:

Diploblechnum fraseri

Common name(s):

Miniature tree fern, Maukurangi

About:

This fern bears a striking resemblance to a miniature tree fern, featuring a slender trunk that can grow up to 1m tall. The broad, sterile fronds extend to approximately 60cm in length, adorned with narrow leaflets that are pinnately divided. These leaflets display a rich, dark green colour and possess a glossy sheen above, complemented by small triangular 'wings' that can be found at their base, right on the stem. In contrast, the fertile fronds are somewhat similar yet slightly smaller, boasting narrower leaflets that differentiate them from their sterile counterparts. This particular fern thrives in relatively dry forest areas located on the North Island, primarily from the King Country region and extending northward, as well as in the upper parts of the South Island. However, it is essential to note that this fern proves to be quite challenging to establish successfully in garden environments, with small plants being the most suitable for transplanting. For optimal growth, it requires a warm site that offers light shade and a dry, clay-based soil composition.
