The loofah (Luffa aegyptiaca, or Luffa cylindrica), also known as sponge gourd or sponge pumpkin, is a fast-growing, annual, tropical crop. It belongs to the pumpkin family (Cucurbitaceae). The plants probably originally come from Africa, Asia and tropical America. In our latitudes, the sponge gourd grows in summer in sheltered locations or in greenhouses or conservatories. The leaves of the loofah cucumber grow on long stems, are lobed, dark green with light spots and grow to around 20 centimeters. The flowers are yellow and reach a diameter of up to five centimeters. When they fall off, they can be picked up and eaten fried. They also taste very good raw in salads. The fruits grow up to 30 centimeters long and look similar to zucchini.
