Acrostichum aureum is a large evergreen fern with fronds up to 3 metres long[
The plant is sometimes harvested from the wild for local use as a food and material for thaching. An ornamental plant, it can be grown in gardens.
Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[
Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase[
Brackish and non-brackish, inundated areas of the tropics, often in or on the margin of mangrove swamps or marshes[
|Other Uses Rating
A plant of the humid lowland tropics and subtropics[
]. Very cold sensitive, it is intolerant of frost[
Requires a permanently moist position and a position with bright, filtered light[
]. Plants can succeed in saline or non-saline conditions - young plants can tolerate a change between the two conditions but older plants become accustomed to either saline or non-saline and are unlikely to survive a change[
Very young leaves - cooked[
The ferns are dried, strung up on rods, and used instead of straw as thatch for the roof[
]. The fronds can be combined with the leaves of Parinari laurinum[
