Longleaf Brake: A Delicate Fern for Tropical and Subtropical Gardens
If you’re looking to add some graceful, feathery texture to your shade garden, the longleaf brake (Pteris longifolia) might just be the fern you’ve been searching for. Also known as luukbedaoch in Palau, this perennial fern brings an elegant, tropical feel to landscapes with its distinctive narrow fronds and arching growth habit.





Where Does Longleaf Brake Come From?
The longleaf brake has quite the travel resume! This fern is native to several regions including the southeastern United States, Puerto Rico, the U.S. Virgin Islands, and even tiny Navassa Island. However, it’s also made itself at home in places where it wasn’t originally found, like Hawaii and various Pacific Basin islands, where it has naturalized and reproduces on its own.
Currently, you can find longleaf brake growing in Alabama, Hawaii, Guam, Palau, Puerto Rico, and the Virgin Islands.
What Makes This Fern Special?
Longleaf brake is technically classified as a forb – a plant without significant woody tissue that keeps its growing points at or below ground level. Don’t let the technical term fool you though; this is simply a delicate, non-woody plant that comes back year after year. Its charm lies in its feathery, narrow leaflets that create an almost lace-like appearance as they arch gracefully from the base.
Should You Plant Longleaf Brake in Your Garden?
The answer depends largely on where you live and what you’re trying to achieve in your landscape. Here are some things to consider:
The Good News
- Low maintenance once established
- Adds beautiful texture and movement to shade gardens
- Perfect for creating that lush, tropical atmosphere
- Works well as ground cover in naturalistic settings
- Thrives in areas where many other plants struggle
Things to Keep in Mind
- Not native everywhere it’s currently growing
- May not provide the same wildlife benefits as native alternatives
- Limited to warmer climates (USDA zones 9-11)
Where Does Longleaf Brake Fit Best?
This fern shines in tropical and subtropical shade gardens, where it can serve as an understory plant or ground cover. It’s particularly at home in naturalized woodland settings and works beautifully alongside other shade-loving plants. The longleaf brake prefers to stay out of wetlands – it’s what experts call an obligate upland plant in the Caribbean, meaning it almost never grows in swampy conditions.
Growing Longleaf Brake Successfully
If you decide to give longleaf brake a try, here’s what you need to know:
Ideal Growing Conditions
- Light: Partial to full shade – this fern doesn’t appreciate harsh, direct sunlight
- Soil: Moist but well-draining soil with good organic content
- Climate: Warm, humid conditions in USDA hardiness zones 9-11
- Moisture: Consistent moisture without waterlogging
Planting and Care Tips
- Choose a shady spot protected from strong winds
- Improve soil with compost or other organic matter before planting
- Apply a layer of organic mulch to help retain moisture
- Water regularly during dry periods, but ensure good drainage
- Remove old or damaged fronds as needed to keep the plant looking tidy
Wildlife and Pollinator Considerations
Since longleaf brake is a fern, it doesn’t produce the flowers that attract pollinators like bees and butterflies. While it may provide some habitat structure, it won’t offer the same level of wildlife support as native flowering plants in your area.
Consider Native Alternatives
If you’re passionate about supporting local ecosystems, consider researching native ferns in your region first. Many areas have beautiful indigenous fern species that provide similar aesthetic appeal while offering better support for local wildlife and maintaining the natural balance of your local ecosystem.
The Bottom Line
Longleaf brake can be a lovely addition to the right garden – one with adequate shade, warmth, and humidity. It’s relatively low-maintenance and brings that coveted tropical fern aesthetic to landscapes. Just remember to consider your local native options first, and always ensure you’re sourcing plants responsibly. Whether you choose longleaf brake or a native alternative, ferns are fantastic for adding texture, movement, and that cool, peaceful feeling that makes any garden feel like a natural retreat.
