Luffa is a versatile vine that produces long gourds, which can be turned into durable sponges. Growing luffa requires 90 to 120 days and a sturdy trellis for support. The vines feature beautiful yellow flowers that attract pollinators. After harvesting, the gourds must be dried thoroughly to create sponges.
