The Story
Plant Bio
Normanbya normanbyi, the black palm, is a tall, solitary Australian palm native to the wet lowland rainforests of northeastern Queensland. It develops a slender, closely ringed trunk that darkens to near-black with age, topped by a prominent silver-green crownshaft and a dense head of plumose fronds.
The large pinnate leaves feature whorled, wedge-shaped leaflets with truncated tips, giving the foliage a distinct bottlebrush appearance that is dark green above and bright silvery-white underneath. In the dry season, it produces branching panicles of green flowers that develop into pear-shaped, reddish-purple fruits.

Planting
How to Grow
- Select a planting site with deep, rich, well-draining soil that retains consistent moisture.
- Provide overhead protection or deep shade for young plants to prevent leaf scorch.
- Water regularly to keep the root zone moist, ensuring the soil never dries out completely.
- Gradually expose the palm to increased sunlight as it matures and grows above the surrounding canopy.
Pro Tip
Establish young plants in deep, filtered shade to mimic their native rainforest understory habitat; exposing seedlings to direct sun causes severe leaf scorch and stunts growth.

Care Guide
Do
- Apply a balanced slow-release palm fertiliser during the warm growing season.
- Allow spent, completely brown fronds to shed naturally or cut them cleanly below the crownshaft.
- Maintain a thick layer of organic mulch around the base to preserve soil moisture.
Don't
- Do not prune green or partially green fronds, as this reduces the plant's energy reserves.
- Never pull off green leaf bases prematurely, which tears the trunk and invites pathogens.
- Do not allow the soil to dry out completely, especially during warm or windy periods.
