The Story
Plant Bio
Phlebodium aureum is an evergreen epiphytic fern native to tropical and subtropical regions of the Americas, where it grows in tree crotches and organic forest debris. It forms a spreading clump of deeply lobed, parchment-like fronds emerging from thick, creeping rhizomes densely covered in golden-brown scales.
The fronds display a glaucous blue-green foliage hue with wavy margins that set it apart from green forest ferns. Prominent round sori line the undersides of the pinnae midribs, producing reproductive spores during warm months.

Planting
How to Grow
- Plant in coarse, well-draining epiphytic potting media such as an orchid bark mix or peat-perlite blend.
- Position the fuzzy, golden rhizomes across the surface of the medium rather than burying them.
- Place in bright indirect light or partial shade, protected from direct midday sun.
- Water thoroughly when the top inch of substrate feels dry, letting excess moisture drain completely.
Pro Tip
Never bury the fuzzy golden rhizomes beneath soil; they must rest directly on the substrate surface to prevent rot.
