Fragrant luffa has a unique fragrance that other luffas do not have. This melon is an old variety in Shanghai and is now rare. Due to low yield, it is rarely seen on the market. The so-called fragrant loofah variety is said to have been introduced from Japan. It looks similar in appearance, bears fruit early, and has many fruit, but the taste does not have the unique fragrance, softness, and slightly sweet flavor. It is also rare in rural areas of Shanghai.
