Gourd 'Sponge Luffa' Seeds (Certified Organic)

Grown for its fibrous flesh which, when dried, makes the best bath sponges ever!

Availability: In stock

All orders are hand-packaged and may take UP TO FOUR weeks to SHIP.
Thank you for your patience during this time.


Make your own bath sponge! The fibrous internal structure of the gourd converts into sponges after 12” long. They climb or spread just like cucumbers and need a very similar growing environment. When ripe at 12” or when the skin feels loose, cut them from the vine and leave in a dry place with good air circulation. The outer skin will come away revealing the luffa beneath. Wash them in mild disinfectant and place in a warm place to dry completely. 

You can also grow these to eat as a vegetable. Luffas are known in Asian Cuisine as “Cee Gwa.” Harvest them for eating when they are 2-6″ long. They can be eaten like a cucumber, or chop and stir-fry with chicken, bamboo shoots, or cashews.
