Phymatosaurus: The Exotic Climbing Fern That’s Making Waves in Tropical Gardens
If you’re looking to add some tropical flair to your garden, you might have stumbled across Phymatosaurus (botanically known as Phymatosorus). This fascinating climbing fern has been quietly establishing itself in warm climates across the United States, and gardeners are starting to take notice of its unique charm.
What Exactly is Phymatosaurus?
Phymatosaurus is a perennial fern that belongs to a group commonly called climbing bird’s nest ferns or basket ferns. Unlike your typical garden fern, this species has a more adventurous spirit – it loves to climb and sprawl, creating dramatic displays with its large, glossy fronds.
You might also see this plant listed under its scientific synonym, Phymatosaurus, which can cause some confusion in plant catalogs and nurseries.
Where Does This Fern Call Home?
Originally from tropical regions of Asia, Australia, and various Pacific islands, Phymatosaurus has found new homes in several U.S. locations. You’ll currently find established populations in Florida, Hawaii, Puerto Rico, and even some U.S. Minor Outlying Islands and Palau.
It’s worth noting that this fern is considered non-native in these locations, having been introduced and now reproducing on its own in the wild.
The Appeal: Why Gardeners Are Falling for This Fern
What makes Phymatosaurus so appealing? Here are the key draws:
- Large, leathery fronds that create bold, tropical textures
- Climbing growth habit that adds vertical interest
- Glossy, attractive foliage that stays looking fresh
- Adaptable to both garden beds and container growing
- Works well as a houseplant in cooler climates
Growing Phymatosaurus Successfully
If you live in USDA hardiness zones 9-11, you can grow Phymatosaurus outdoors year-round. In cooler zones, it makes an excellent houseplant that can spend summers outside.
Ideal Growing Conditions
- Light: Bright, indirect light or partial shade
- Humidity: High humidity levels (60% or higher)
- Soil: Well-draining, rich organic matter
- Water: Consistent moisture without waterlogging
- Support: Provide climbing structures like tree trunks or trellises
Care Tips for Happy Ferns
Caring for Phymatosaurus isn’t too demanding once you understand its preferences:
- Water regularly but ensure good drainage – soggy roots spell trouble
- Mist frequently to maintain humidity, especially indoors
- Feed monthly with diluted liquid fertilizer during growing season
- Remove dead or damaged fronds to keep plants looking tidy
- Provide sturdy support for climbing varieties
Garden Design Ideas
Phymatosaurus works beautifully in:
- Tropical and subtropical landscape designs
- Shade gardens where you need bold texture
- Naturalistic plantings that mimic rainforest understories
- Container gardens on patios and decks
- Indoor plant collections with adequate humidity
A Word About Native Alternatives
While Phymatosaurus can be a stunning addition to appropriate gardens, consider exploring native fern options first. Native plants typically require less maintenance, support local wildlife better, and help preserve regional ecosystems. Research native ferns in your area that might provide similar aesthetic appeal.
The Bottom Line
Phymatosaurus offers tropical gardeners an opportunity to grow something a bit different – a climbing fern with personality and presence. While it’s not native to U.S. locations where it now grows, it doesn’t appear to be problematically invasive either. If you’re drawn to its unique growth habit and glossy foliage, and you can provide the humid, shaded conditions it craves, this could be an interesting addition to your plant collection.
Just remember to source plants responsibly, maintain them properly, and always consider native alternatives that might serve your garden’s needs just as well while supporting local ecosystems.
