Southern Brackenfern: A Native Fern for Warm Climate Gardens
If you’re looking to add some native greenery to your Florida or Puerto Rican landscape, you might want to get acquainted with southern brackenfern (Pteridium caudatum). This perennial fern brings a touch of wild, natural beauty to gardens while supporting local ecosystems.
What is Southern Brackenfern?
Southern brackenfern is a native perennial fern that belongs to the bracken family. Unlike its more widespread cousin, this species has adapted specifically to the warm, humid conditions of the southeastern United States and Caribbean. As a forb, it’s an herbaceous plant without woody stems, sending up fresh fronds from underground rhizomes each growing season.
You might also see this fern listed under its synonyms Pteridium aquilinum var. caudatum or Pteridium aquilinum ssp. caudatum in older botanical references, but Pteridium caudatum is the currently accepted scientific name.
Where Does Southern Brackenfern Grow?
This native beauty has a fairly limited natural range compared to other bracken ferns. You’ll find southern brackenfern growing wild in Florida and Puerto Rico, where it has adapted to local climate conditions and soil types.
Identifying Southern Brackenfern
Like other bracken ferns, southern brackenfern produces distinctive triangular fronds that emerge from underground rhizomes. The fronds typically have that classic fern appearance with multiple divisions, creating a lacy, delicate texture that’s instantly recognizable as ferny. The plant spreads via underground rhizomes, which is typical behavior for bracken species.
Is Southern Brackenfern Right for Your Garden?
As a native species, southern brackenfern can be a wonderful addition to naturalistic landscapes and woodland gardens within its native range. Here’s what to consider:
The Good:
- Native to Florida and Puerto Rico, supporting local ecosystems
- Perennial growth means it returns year after year
- Adds natural texture and movement to garden spaces
- Well-adapted to local climate conditions
- Requires minimal maintenance once established
Things to Keep in Mind:
- Like other bracken ferns, it may spread via underground rhizomes
- Limited information available about cultivation requirements
- May not be readily available in nurseries due to its specialized range
Growing Southern Brackenfern Successfully
While specific cultivation information for southern brackenfern is limited, you can draw from general bracken fern growing principles. These ferns typically prefer:

Given its native range in Florida and Puerto Rico, southern brackenfern is likely suited to USDA hardiness zones 9-11, thriving in warm, humid conditions year-round.
Where to Find Southern Brackenfern
Due to its limited native range, southern brackenfern may be challenging to find at typical garden centers. Your best bet is to contact native plant societies in Florida or specialty native plant nurseries that focus on regional flora. Always ensure any plants you purchase are responsibly sourced and not collected from wild populations.
The Bottom Line
