Luffa is a genus of tropical and subtropical vines in the cucumber family. The most well-known species is Luffa aegyptiaca, commonly referred to as sponge gourd or Egyptian cucumber. Luffa plants produce large, elongated fruits that resemble cucumbers when young. As they mature, the fibrous interior develops into a network of tough, sponge-like fibers. When dried and peeled, these fibers are used as natural exfoliating sponges, commonly known as loofahs. In addition to their use as sponges, young luffa fruits are edible and can be cooked and consumed like other gourds. Luffa plants thrive in warm climates and require a long growing season to fully mature. They are often grown on trellises to support their vigorous vine growth and heavy fruits.
