Vegetable Fern (Pako') - Athyrium esculentum


For a change, try fern vegetable. It's good for the family;  It is rich in minerals and high in food value.

Pako' abounds in the wild - fields, forests and on river banks. It is often found growing on the backyard and idle lots.  Because many people have learned to eat pako', it is now widely sold in public markets just like any vegetable. 

Gather the young leaves or fronds which are eaten either raw or cooked.  They may be used as salad with various dressings, as leafy vegetable, or as ingredient of stews.

At home we prefer Ilocos Vinegar for dressing, with chopped onions, and a dash of salt.  Try fresh tomato instead of vinegar. 

When cooking bulanglang or diningding, include pako' singly ir in combination with other vegetables like spinach and eggplant.  Don't forget sweet potato (kamote) in  cubes as thickening (buridibud).

How do you recognize the plant in the field? Here is a guide.  Refer to the illustration to familiarize yourself.  Pako' is in ther list of wild food plants, and "hunger" or emergency food plant in times of scarcity. It is a survivor's alternative food.  

Athyrium esculentum has twce- or thrice-pinnate frond which are 50 to 80 cm long and about half as wide.  The pinnules are pointed, coarsely serrate, and about 2 to 5 cm long. The plant is abundantly distributed in the Philippines growing on gravelly bars and banks of streams.  It is also found growing widely from India to Polynesia.
