About

Luffa aegyptiaca, the sponge gourd, Egyptian cucumber or Vietnamese luffa, is an annual species of vine cultivated for its fruit, native to South and Southeast Asia.

How to grow it

Luffa has been cultivated throughout Asia for centuries for use as a household cleaning agent and is now, due to the gently abrasive quality of the natural fibers, a popular exfoliating agent in the eco-friendly cosmetic industry. Owing to its striking yellow flowers, the plant is occasionally grown as an ornamental.
