This perennial beauty has been gracing the Hawaiian Islands long before any of us arrived, and it’s ready to bring that same natural magic to your landscape.
What Makes Spreading Spleenwort Special?
The spreading spleenwort is a true Hawaiian native, found naturally across the island chain.

Growing Conditions: Keep It Cool and Moist
Spreading spleenwort is happiest when you recreate conditions similar to its natural Hawaiian forest habitat:
- Light: Shade to partial shade (avoid direct sunlight)
- Soil: Well-draining but consistently moist, rich in organic matter
- Humidity: High humidity levels (typical of Hawaiian climates)
- Climate: USDA zones 10-12 only – this is strictly a tropical plant
Planting and Care Tips
Getting your spreading spleenwort established is straightforward if you follow these guidelines:
- Choose a location with reliable shade and protection from strong winds
- Prepare the soil with plenty of organic compost or leaf mold
- Plant at the same depth it was growing in its container
- Water regularly to keep soil consistently moist but never waterlogged
- Mulch around the base to help retain moisture and suppress weeds
- Be patient – ferns generally establish slowly but are worth the wait
A Note About Sourcing
When purchasing spreading spleenwort, make sure to buy from reputable nurseries that specialize in native Hawaiian plants. This ensures you’re getting properly sourced material that won’t impact wild populations.
