Luffa Angled ‘Bonanza’ Seeds – Chinese Okra | Edible & Luffa Sponge Gourd

Luffa Angled ‘Bonanza’ (Luffa acutangula) is a vigorous, highly productive climbing vine prized across Asia for its large, tender, deeply ridged fruits — harvested young for eating as a delicious vegetable, or allowed to fully mature and dry on the vine to produce natural luffa sponges. Known as Chinese Okra in the West, this is an entirely different plant from smooth luffa (L. cylindrica) — its distinctive angled ridges running the length of each fruit make it immediately recognizable and give the vegetable a uniquely satisfying texture in the kitchen.

Fruits reach up to 18 inches long and 2 inches in diameter, weighing just under one pound, with smooth green skin and pale, sweet flesh. Remarkably fast to produce: fruits are table-ready just 45 days after flowering. Plants are vigorous climbers — train on a sturdy trellis or vertical support for best results, improved air circulation, and straighter, easier-to-harvest fruit.

Culinary Uses

• Harvest young (8–12 inches) for best eating quality — flesh is tender, mild, and slightly sweet
• Stir-fries, soups, and curries across Chinese, Indian, Vietnamese, and Filipino cuisines
• Shoots and flower buds are also edible — use in stir-fries as a delicate green vegetable
• Peel the ridges before cooking; the skin between the ridges can be left on young fruit
• Substitutes for zucchini or summer squash in most cooked preparations

Luffa Sponge Production

• Allow fruits to fully mature and dry completely on the vine until the skin turns brown and papery
• Once dry, the outer skin peels away easily to reveal the fibrous interior sponge
• Shake out seeds and rinse the sponge — bleach lightly in diluted solution if desired for a cleaner finish
• Natural, biodegradable sponges for kitchen, bath, and body use

Planting Guide

• Sow outdoors in warm soil after all frost danger has passed — or start indoors 3–4 weeks before last frost in individual pots.
• Seed preparation: Soak seeds in warm water for 12–24 hours before sowing, or lightly scarify the seed coat to improve germination.
• Soil: Rich, well-draining, fertile soil in full sun. Amend with compost before planting.
• Spacing: Sow seeds 12–18 inches apart; allow 4–6 feet between rows. Provide a sturdy trellis or vertical support at least 6 feet tall.
• Watering: Keep soil consistently moist, especially during fruit development.
• Fertilizing: Apply a balanced fertilizer at planting; side-dress with compost or liquid fertilizer once vines begin to run.
• Harvest: Pick fruits young and frequently — regular harvesting encourages continued production. Overmature fruit becomes fibrous and bitter.
