  • Luffa on vine

This type of squash while not strictly a vegetable can be eaten when young. They are more commonly grown to use when mature and dried.

The plants need warmth to grow successfully. Keep inside until all risk of frost is gone.

They grow on vines similar to cucumbers.

A large loofa makes a great back scratcher. Luffa can be cut into many shapes for scrubbing pads, padding, and other uses.

Culinary hints - cooking and eating Luffa

The luffa flowers and fruits are soft and edible when young and are sometimes cooked and eaten like squash or okra. Loofah has been an important food source in many Asian cultures. The leaves and vines should not be eaten.

Hi Zarina, I don't know anything about this company that is located in your area, but I found a local seed company called Seeds and Plants South Africa. Not all seed companies offer luffa seeds as you probably have discovered no matter where you garden. The website site looks very professional with a wide variety of selections. The Best, Donna

I live in Las Vegas Nevada. It gets very hot during the summer months (100 to 120°). Will the loofahs grow here?

Yes! I live in south Spain which is zone 9b/10a and grew loofah plants successfully in 2021. We had a couple of weeks over 40c (105f) and it grew like crazy! Use straw mulch and water well twice a week.
