The Story
Plant Bio
Parablechnum novae-zelandiae is a large, evergreen terrestrial fern native to New Zealand, where it colonizes damp forest floors and coastal gullies. It spreads slowly via creeping rhizomes to produce dense colonies of long, arching fronds.
The sterile fronds emerge with striking pink, bronze, or bright red-orange coloration before maturing to a deep, glossy green. Narrow, upright fertile fronds rise above the sterile foliage, turning dark brown as their spores mature.

Planting
How to Grow
- Select a planting site in partial to dappled shade with humus-rich, loamy, or clay soil.
- Amend the soil with organic matter or leaf mold to ensure a highly moisture-retentive yet well-drained structure.
- Plant the crown at soil level, watering thoroughly to settle the soil around the creeping rhizomes.
- Apply a thick layer of organic mulch to conserve soil moisture and protect the roots from drying out.
Pro Tip
Maintain constant soil moisture to prevent the delicate frond margins from permanently scorching, and avoid high-salt synthetic chemical fertilizers which burn the root system.

Care Guide
Do
- Water regularly to keep the soil consistently moist, especially during dry summer periods.
- Apply a top-dressing of rich leaf mold or compost in spring to provide gentle nutrients.
- Use rainwater or soft water if possible to prevent lime and calcium buildup in the soil.
Don't
- Do not allow the soil to dry out completely, as drought causes immediate frond scorch and dormancy.
- Do not apply high-salt synthetic chemical fertilizers that can burn the sensitive root system.
- Do not shear into old, leafless wood when cleaning up the plant.
