Luffa Gourd Seeds – Non-GMO Heirloom 0.5oz

Grow Your Own Natural Sponges from Heirloom, Non-GMO Luffa Gourd Seeds

Luffa is the plant behind the bath sponge. Our heirloom luffa gourd seeds (Luffa aegyptiaca) grow into vigorous vines that can run 15 to 30 feet, with big yellow flowers and long green gourds. Picked young, the gourds cook like zucchini; left to mature and dry, they become fibrous, long-lasting sponges for the bath and the kitchen. This 0.5 oz bulk pack holds roughly 150 seeds.

Who it's for

Great for gardeners with a long, warm season and a sturdy trellis, for homesteaders and zero-waste households, and for anyone who wants a fun, useful project to grow with kids.

How & when to plant

Luffa needs 150 to 200 warm days, so start early. Soak seeds 24 hours, then sow indoors 4 to 6 weeks before the last frost, 1/2 to 1 inch deep in individual pots. Transplant after all danger of frost when the soil is warm, 2 to 3 feet apart at the base of a strong trellis or fence. In long-season areas, direct sow after frost. Seedlings appear in 7 to 14 days. Our luffa growing guide has the complete timeline.

Growing & care

Give luffa full sun, rich soil with plenty of compost, and steady water. The heavy vines need a strong trellis, arbor, or fence so the gourds hang straight and stay clean. Feed monthly and mulch well. Bees pollinate the flowers; hand pollinate if fruit set is slow.

Harvest

For eating, pick gourds under 6 inches long while still tender. For sponges, leave the gourds on the vine until the skin turns yellow-brown and feels light and papery, then peel off the skin, shake out the seeds, rinse the fiber, and dry it in the sun. Save the black seeds for next year.

Benefits & uses

One luffa vine gives you food, natural sponges, shade for a porch or pergola, and big flowers for pollinators. The sponges are compostable and last for months.
