Oceaniopteris gibba, the miniature tree fern (syn. Blechnum gibbum), is a tropical species of fern in the family Blechnaceae, native to New Caledonia and introduced in Fiji.[1] It has received the Royal Horticultural Society's Award of Garden Merit.[2]
It grows to NaNm (-2,147,483,648feet). With a vertical "trunk" (actually a rhizome), it has bright green fronds. As it does not tolerate temperatures below 15C, in temperate zones it must be cultivated under glass all year round. It is a suitable subject for a greenhouse or conservatory. It requires an acid soil and a partially shaded position.[2]
