{"type":"firestarter.listing","listing":{"id":"lst_GbU4kEx4","product_name":"Luffa Gourd","category":"Vegetables","description":"This is one of the most rewarding and remarkable plants you can add to your garden. It’s a vigorous, climbing vine that produces a natural sponge. The plant itself is a beautiful ornamental, with silvery-green foliage and bright yellow blossoms that will happily scale a strong fence or trellis, growing up to 20 feet. It's truly fascinating to watch the 12- to 24-inch gourds develop over the season.\n\nThe real magic comes at the end of the year. Once matured and dried on the vine, the gourds' fibrous interior is revealed—a perfect, all-natural, biodegradable sponge. It's the ultimate plastic-free alternative for scrubbing dishes, cleaning, or exfoliating in the bath. This is a very long-season (130 days) and heat-loving plant. To ensure you get a full harvest of usable sponges, northern gardeners will need to start seeds indoors and give them a good head start.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/files/luffa.png?v=1764182526","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/luffa_4.png?v=1764182536","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/luffa_2.png?v=1764182536","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/luffa_6.png?v=1764182536","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/luffa_3.png?v=1764182536","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/luffa_5.png?v=1764182536"],"price":5.79,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:34.339Z"},"share_url":"https://firestarter.network/l/lst_GbU4kEx4","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
