Who grows luffa sponges in the US?

In the U.S., luffa sponges are primarily grown by small-scale farmers and gardeners, particularly in warmer regions like California, Florida, and the southern states. These farmers cultivate luffa gourds, which are harvested when mature and processed to create natural sponges. Additionally, some specialty farms and organic growers focus on luffa production to meet increasing consumer demand for eco-friendly and biodegradable products.
