Lidgate’s Brake: Hawaii’s Critically Endangered Native Fern
Meet Lidgate’s brake (Pteris lydgatei), one of Hawaii’s most precious and precarious native ferns. This delicate beauty isn’t your typical garden center find – it’s a critically endangered species that tells an important story about Hawaii’s unique botanical heritage and the urgent need for plant conservation.
What Makes Lidgate’s Brake Special?
Lidgate’s brake belongs to the brake fern family (Pteridaceae) and is found nowhere else on Earth except Hawaii. This endemic fern produces the characteristic feathery, delicate fronds that make brake ferns so appealing, but what truly sets it apart is its rarity. With a Global Conservation Status of S1 (Critically Imperiled), this species has only five or fewer known occurrences and fewer than 1,000 individual plants remaining in the wild.
As a perennial fern, Lidgate’s brake would naturally persist year after year in its native habitat, contributing to the complex understory ecosystem of Hawaiian forests. The species was historically also known by the synonym Schizostege lydgatei, but today it’s recognized under its current botanical name, Pteris lydgatei.
Where Does It Grow?
This rare fern is endemic to Hawaii, meaning it evolved here and exists nowhere else naturally. Within the Hawaiian islands, it occupies very specific habitat niches, typically in moist, shaded areas of native forests. Its wetland status as Facultative Wetland means it usually thrives in wetland conditions but can occasionally be found in drier areas.

Should You Grow Lidgate’s Brake?
Here’s where things get serious. Because of its critically imperiled status, Lidgate’s brake requires special consideration. If you’re passionate about Hawaiian native plants and conservation, this fern could be an important addition to a native garden – but only under very specific circumstances:
- Source responsibly: Only obtain plants from reputable native plant nurseries that can verify the plants were propagated legally and ethically
- Never collect from the wild: Taking plants from their natural habitat could push this species closer to extinction
- Consider it a conservation project: Growing this fern is less about typical gardening and more about participating in species preservation
Growing Conditions and Care
If you do obtain Lidgate’s brake through responsible channels, it will thrive in conditions that mimic its native Hawaiian forest habitat:
- USDA Hardiness Zones: 10-11 (tropical and subtropical climates only)
- Light: Partial to full shade, protected from direct sunlight
- Moisture: Consistently moist soil, as befits its facultative wetland status
- Soil: Well-draining but moisture-retentive, rich organic matter
- Humidity: High humidity levels similar to tropical forest conditions
Garden Role and Design Ideas
In the right setting, Lidgate’s brake can serve as:
- A ground cover in shaded native Hawaiian gardens
- An accent plant in conservation-focused landscapes
- Part of a specialized collection of rare Hawaiian natives
- An educational specimen in botanical gardens or nature centers
The Conservation Conversation
Growing Lidgate’s brake isn’t just about adding another pretty fern to your garden – it’s about participating in the critical work of preserving Hawaii’s unique biological heritage. Every responsibly grown plant represents hope for this species’ survival and serves as a living reminder of what we stand to lose when native habitats disappear.
If you’re interested in supporting Hawaiian native plants but can’t find Lidgate’s brake through responsible sources, consider other native Hawaiian ferns that are less critically endangered. Your local native plant society or botanical garden can point you toward alternatives that will give you that lush, tropical fern look while supporting conservation efforts.
Remember: when it comes to critically endangered species like Lidgate’s brake, every plant matters. Choose wisely, source responsibly, and help ensure that future generations can marvel at Hawaii’s incredible endemic flora.
