Katuray
Also known as: Agati (Indian subcontinent usage) · Vegetable hummingbird tree (English descriptive name) · Katuray na pula (red-flowered ornamental form)
Definition
Katuray (Sesbania grandiflora), also called vegetable hummingbird or agati, is a fast-growing small tree widely grown in Philippine backyards and farms for its large edible white flowers and tender young pods. Beyond the kitchen it serves as a nitrogen-fixing shade and hedgerow tree, which explains its popularity in traditional agroforestry across Southeast Asia. (Wikipedia — Sesbania grandiflora)

- Katuray na pula (red-flowered ornamental form)
Examples and Analogies
- Backyard salad tree: Katuray functions in the provincial garden the way a malunggay tree does — a standing source of fresh vegetables that needs almost no care.
- Living fence: Like ipil-ipil in hedgerows, a row of katuray doubles as a boundary marker that feeds the soil while shading crops.
Usage Scenarios
1. Home Cooking
White flowers are blanched for salads with bagoong or calamansi, or dropped into sinigang and dinengdeng for color and a mild, bean-like flavor.
2. Farm Hedgerows
Planted along field borders, the tree fixes nitrogen, drops leaf litter as green manure, and can be lopped for livestock fodder.
3. Quick Canopy Establishment
Its extremely rapid first-year growth is used to shade newly planted coffee or cacao seedlings.
Strategies
- Harvest flowers in the morning when buds are freshly opened for the best texture
- Prefer white-flowered trees for food; red-flowered forms are mainly ornamental
- Coppice mature trees low to keep flowers within hand reach and stimulate new blooming wood
Security and Safety Measures
- Cook or blanch flowers before eating, as with other legume vegetables, to neutralize antinutritional compounds
- Do not consume seeds or mature pods in quantity, which are not used as food
- Site trees away from drainage canals since seedlings establish aggressively in wet ground
Historical Context
Katuray arrived in Philippine gardens through ancient trade circuits that linked the archipelago to South and Southeast Asia, where the species has long been both a vegetable tree and a medicinal plant. Folk medicine across the region assigned its leaves and flowers roles in treating minor ailments, while its flowers entered everyday regional cookery — most visibly in Ilocos and the Visayas, where blossoms appear in market vegetable bundles. Its scientific description in the eighteenth century formalized what farmers already knew: few trees convert soil, sunlight, and kitchen demand into food so efficiently.
Challenges and Controversies
- Limited commercial development despite steady backyard demand, leaving the flower a niche market vegetable
- Occasional confusion between edible white-flowered trees and purely ornamental red forms, which discourages first-time cooks
