Vegetable fern (Diplazium esculentum) is an edible fern found throughout Asia and Oceania. It is probably the most commonly consumed fern.[1] The young fronds are stir-fried as a "vegetable" or used in salads.[2][3]

In Hawaii it is used to make pohole.

Description[edit]

It is known as pucuk paku in Malaysia, paco in the Philippines,[2] dhekia (ঢেকীয়া) in Assam "Dhenkir Shaak (ঢেঁকির শাক) in Bengali, and linguda in northern India, referring to the curled fronds. In Thailand it is known as phak khut (Thai: ผักกูด). They may have mild amounts of fern toxins but no major toxic effects are recorded.[4]

Diplazium esculentum is sometimes grown as a house plant.

The genus Diplazium is in the family Athyriaceae, in the eupolypods II clade[5] of the order Polypodiales,[6] in the class Polypodiopsida.[7]
