Hawai’i Umbrella Fern: A Rare Hawaiian Native Worth Protecting
Meet the Hawai’i umbrella fern (Sticherus owhyensis), a unique native Hawaiian fern that’s as special as it is elusive. This perennial beauty is one of those plants that makes you feel like you’re discovering a hidden treasure in the islands’ rich botanical heritage.
What Makes This Fern Special?
The Hawai’i umbrella fern belongs to the Gleicheniaceae family and was previously known by the scientific name Gleichenia owhyensis. As a forb-type fern, it lacks the woody tissue you’d find in shrubs or trees, instead maintaining soft, herbaceous growth throughout its perennial lifecycle.
What sets this fern apart is its rarity. With a Global Conservation Status of S3 (Vulnerable), this species is considered at risk due to its limited range and small population numbers. Typically, there are only 21 to 100 known occurrences of this fern, with an estimated 3,000 to 10,000 individuals remaining in the wild.
Where You’ll Find It
This endemic Hawaiian species calls only the Hawaiian Islands home, making it a true local specialty. The Hawai’i umbrella fern typically grows in upland areas, though it can occasionally be found in wetland conditions as well.
Should You Grow This Rare Beauty?
Here’s where things get a bit complicated. While this fern would make a fascinating addition to any native Hawaiian plant collection, its vulnerable status means we need to be extra careful about how we approach cultivation.
The Conservation Consideration
If you’re interested in growing the Hawai’i umbrella fern, please ensure you’re working with:
- Responsibly sourced plant material from reputable native plant nurseries
- Plants that have been ethically propagated, not collected from wild populations
- Guidance from local conservation organizations or botanical gardens
Garden Role and Landscape Use
When responsibly sourced, this fern could serve as:
- A unique specimen plant in native Hawaiian gardens
- An educational piece in conservation-focused landscapes
- Part of habitat restoration projects
- A conversation starter about Hawaiian endemic plants
Growing Conditions
Based on its natural habitat preferences, the Hawai’i umbrella fern likely thrives in:
- Areas that mimic Hawaiian upland conditions
- Locations with good drainage (given its facultative upland status)
- Spots that provide some protection from harsh elements
- Environments suitable for other Hawaiian native ferns
Unfortunately, specific care requirements for this rare species aren’t well-documented in cultivation guides, which is another reason to work with experienced native plant specialists if you’re considering growing it.
The Bottom Line
The Hawai’i umbrella fern represents both an opportunity and a responsibility. While it could be a stunning addition to the right garden, its vulnerable status means that any cultivation should be done thoughtfully and ethically. If you’re passionate about Hawaiian native plants, consider supporting conservation efforts for this species first, and only pursue growing it if you can ensure you’re doing so responsibly.
Remember, sometimes the best way to appreciate a rare plant is to support its conservation in the wild while exploring other native Hawaiian ferns that might be more readily available for garden use.
