- Phonetic Spelling

- Description
-
This epiphytic fern is native to the tropical eastern coasts of the Americas and is commonly grown as a houseplant. It is a rhizomatous fern, spreading by its roots that are densely covered in golden scales, giving the fern its name. Ideal growing conditions include partial sun, medium humidity and moist but not soggy, soil.
The fronds are large and deeply lobed, from 12-50 inches long and 4–20 inches wide, in the wild. The evergreen fronds have up to 35 pinnae that vary in color from bright green to green-blue or silver-green or gray-green in some cultivars. They have undulate margins. Spore sori are round and run along each side of the pinna midrib. The tiny spores are wind-dispersed.
Insects, Diseases, and Other Plant Problems:
Monitor for spider mites, thrips, Florida Fern Caterpillar, and fungus gnats. Potential diseases include crown rot and root rot. Browning of fronds usually indicates that the plant needs higher humidity while curling is common symptom of low humidity and underwatering .
