Neobrackenridge’s Spleenwort: A Rare Hawaiian Native Fern
If you’re passionate about native Hawaiian plants and have a thing for unique ferns, you might have stumbled across the name Neobrackenridge’s spleenwort (Asplenium neobrackenridgei). This perennial fern is one of Hawaii’s botanical treasures, though it’s not exactly the kind of plant you’ll find at your local garden center.
What Makes This Fern Special
Neobrackenridge’s spleenwort is a native Hawaiian fern that belongs to the diverse Asplenium genus, commonly known as spleenworts. Like other members of its family, this fern produces delicate, divided fronds that create beautiful texture in shaded garden spaces. As a perennial, it maintains its presence year-round in suitable conditions.
Where You’ll Find It Growing Wild
This special fern calls Hawaii home and is found nowhere else in the world. It’s what botanists call an endemic species – meaning it evolved specifically in the Hawaiian Islands and exists naturally only there.
The Challenge of Growing Neobrackenridge’s Spleenwort
Here’s where things get a bit tricky for the average gardener. Asplenium neobrackenridgei appears to be quite rare, with very limited information available about its specific growing requirements, availability, or conservation status. This isn’t necessarily a plant you can simply order online or pick up at a nursery.
If You’re Interested in Hawaiian Spleenworts
While specific care information for Neobrackenridge’s spleenwort is scarce, most Hawaiian Asplenium species share similar growing preferences:
- Shade to partial shade conditions
- High humidity environments
- Well-draining, organic-rich soil
- Protection from strong winds
- Consistent moisture without waterlogging
These ferns typically thrive in USDA hardiness zones 10-12, making them suitable for tropical and subtropical climates.
A Word About Responsible Gardening
If you’re lucky enough to encounter this fern or learn more about its availability, remember that rare native plants deserve special consideration. Always source plants from reputable nurseries that practice ethical propagation methods. Never collect plants from the wild, especially rare Hawaiian endemics that may be struggling with habitat loss.
Alternative Hawaiian Ferns to Consider
If you’re drawn to the idea of growing Hawaiian native ferns but can’t find Neobrackenridge’s spleenwort, consider looking for other native Hawaiian Asplenium species or ferns that may be more readily available through specialized native plant nurseries. These alternatives can still give you that authentic Hawaiian forest feel while supporting native plant conservation efforts.
The Bottom Line
Neobrackenridge’s spleenwort represents the incredible botanical diversity of Hawaii, but it’s not a plant for the typical home gardener. If you’re serious about Hawaiian native plant conservation and have access to specialized resources, this fern could be a meaningful addition to a dedicated native Hawaiian landscape. For most gardeners, however, exploring more readily available Hawaiian native ferns might be a more practical way to support native plant gardening while still enjoying the beauty of island flora.
