Brake Fern (Pteris ×delchampsii): A Mysterious Native Hybrid

If you’re a fern enthusiast looking for something truly unique for your Florida garden, you might have stumbled across references to the brake fern, scientifically known as Pteris ×delchampsii. But here’s where things get interesting – and a bit mysterious.

What Exactly Is This Brake Fern?

Pteris ×delchampsii is listed as a perennial plant native to the United States, but don’t expect to find it at your local nursery anytime soon. The × in its botanical name indicates this is a hybrid – essentially a cross between two different Pteris species. While the parent species aren’t clearly documented, this particular hybrid appears to be extraordinarily rare or possibly no longer exists in cultivation.

Where Does It Grow?

According to available records, this brake fern is native to Florida, making it a true Sunshine State specialty. However, its current status and exact locations within Florida remain unclear.

The Reality Check for Gardeners

Here’s the thing about Pteris ×delchampsii – while it’s documented as a native species, finding reliable information about its appearance, growing requirements, or even current existence proves challenging. This isn’t uncommon with hybrid ferns, especially those that may have been rare to begin with.

What This Means for Your Garden

If you’re interested in growing native brake ferns in Florida, you might want to consider these alternatives that are more readily available:

  • Chinese brake fern (Pteris vittata) – though not native, widely available
  • Native Florida ferns from other genera that are easier to source
  • Consulting with local native plant societies about confirmed Pteris species in your area

The Bottom Line

While Pteris ×delchampsii holds the appeal of being a native Florida fern, its rarity and limited documentation make it more of a botanical curiosity than a practical garden choice. If you’re passionate about growing native ferns, focus on well-documented species that you can actually find and successfully grow.

Sometimes in gardening, the most interesting plants are the ones that remain just out of reach – and this mysterious brake fern certainly fits that description!
