Acrostichum aureum

Acrostichum aureum

Acrostichum aureum L. — first published in Sp. Pl.: 1069 (1753) — is one of the world’s most remarkable and ancient ferns, known commonly as the Golden Leather Fern or Mangrove Fern. Native to tropical and subtropical coastal regions worldwide, including Ecuador, this intermediate to warm-growing species from the Pteridaceae family thrives in brackish and freshwater wetlands, mangrove edges, and humid tropical forests. It is one of the largest ferns in the world, capable of producing magnificent arching fronds that can reach 2–3 meters in length, making it a truly spectacular specimen plant for tropical gardens and large indoor spaces.

Features

  • Fronds: Enormous, arching, pinnate fronds in rich deep green — among the largest of any fern species in the world
  • Fertile fronds: Upper pinnae are covered in golden-brown sporangia on the underside — the feature that gives it the name "Golden" Leather Fern
  • Growth habit: Large, clumping terrestrial fern; forms impressive colonies in its natural habitat
  • Classification: L. — first published in Sp. Pl.: 1069 (1753); one of Linnaeus’s original described species
  • Origin: Pantropical — coastal wetlands, mangroves, and humid forests worldwide including Ecuador

Care Guide

  • Light: Bright filtered light to partial shade; avoid intense direct midday sun which can scorch the fronds
  • Temperature: Intermediate to warm, between 18°C and 30°C (64°F – 86°F); protect from cold and frost
  • Watering: Keep consistently moist to wet; tolerates waterlogged conditions and is one of the few ferns that thrives with its roots in standing water
  • Humidity: High, 70–90%; thrives in very humid tropical conditions
  • Soil: Rich, moisture-retentive soil; tolerates a range of substrates including heavy clay and brackish conditions

Acrostichum aureum is a fern with a history as long as botany itself — described by Linnaeus in 1753 and found on tropical coastlines across the globe. Its enormous, arching fronds bring a prehistoric grandeur to any space, and its tolerance for wet conditions makes it uniquely versatile. A majestic species for the grower who thinks big.
