Where it grows wild

Shaded, moist banks, streamsides and forest floors in lowland and hill forest, where the Austroblechnum parents grow. Details for the hybrid itself are thin; this is inferred from its relatives and the records.

Recorded from about 30 to 440 m, median about 200 m (few records carry an elevation).
