Sigarilyas
Definition
Sigarilyas is the Filipino name for the winged bean (Psophocarpus tetragonolobus), a climbing tropical vine whose pods bear four distinctive frilly “wings” running along their length. Practically the entire plant is edible — the crisp, winged pods, the leaves, the flowers, the young tuberous roots, and the mature seeds — a versatility that earned it the nickname “wonder bean” in international agricultural literature. In the Philippines the young pods are the most familiar form, sauteed or added to vegetable dishes for their asparagus-like crunch.

Also Known As
Winged bean; asparagus pea (loosely); four-angled bean; goa bean; sigarilyas (Tagalog and Visayan markets).
Examples and Analogies
If sitaw is the everyday pole bean of Filipino cooking, sigarilyas is its fancy winged cousin: cut into diamonds, its pods look like they have been trimmed with lace, and they bring a similar green-bean sweetness with a firmer snap.
Usage Scenarios
Cooks stir-fry sigarilyas with garlic and shrimp or mix it into chopseuy and other vegetable medleys, taking advantage of slices that hold their shape and crunch. Nutrition and gardening programs promote the species because it enriches soil with nitrogen, grows on simple trellises, and supplies protein from multiple plant parts.
Strategies
Growers trellis the vigorous vines high, harvest pods while still flat and tender, and manage harvest frequency to keep plants productive through the season. Research interest in Papua New Guinea and Southeast Asia during the 1970s–80s positioned the species as a multipurpose protein crop, and hobby gardeners still save seed from mature pods.
Security and Safety Measures
Young winged-bean pods cooked as a vegetable are the established food use; mature raw seeds contain antinutritional factors and should not be eaten raw, while tuberous roots are eaten cooked in other cuisines and are consumed sparingly. Routine washing and thorough cooking apply as with all garden legumes.
Historical Context
The winged bean’s wild ancestry traces to Africa, with long cultivation in Papua New Guinea and Southeast Asia; it reached or was long established in Philippine gardens as a minor vegetable recorded in colonial-era crop lists. Its moment of global attention came in the late twentieth century when development agencies championed it as an underexploited tropical protein source, boosting research collections across the region, including Philippine trials.
Challenges and Controversies
Despite its one-time “wonder crop” billing, sigarilyas never broke out of niche status: pod yields and labor requirements lag behind mainstream beans, and market familiarity remains limited mostly to traditional home gardens — a case study often cited in debates about why promising underutilized crops fail to scale.
