If you’ve spent most of your life underneath the impression that loofahs are some kind of sea sponge and that these scratchy pure scrubbers are the final thing you’d need to use on your physique on a day by day foundation, you’re not alone. But the truth is, the Luffa Aegyptiaca (usually often known as loofah in the U.S.) is the taxonomic title of a species of gourd that grows on land, and it’s a genetic descendant of the wild cucumber. What’s extra, if it’s regionally grown with minimal processing, it’s lots mushy sufficient for not simply your pores and skin, however loads of different purposes, too.
What is a luffa?
In the States, you’d be excused for not being conversant in this distinctive plant, as luffa is much extra widespread in Asia and tropical areas. In truth, only a few farmers grow the plant commercially for the American market—there are simply two farms in the nation and, in accordance to Brooklynn Gamble, farm supervisor at The Luffa Farm in Nipomo, California, each are positioned in the West Coast state. But the plant isn’t endemic to international locations this far north, so cultivating it requires numerous care and a spotlight.
Fortunately, luffa farmer Deanne Coon was keen to supply each, which is how The Luffa Farm was born in 2000 after rising the plant as a part of a buddy’s biology class experiment after which spending practically 20 years experimenting. Thanks to Nipomo’s location in a decidedly non-tropical local weather, Coon had to account for issues like cooler seasons (she grows in greenhouses), coastal winds (additionally greenhouses) and gophers (she grows vegetation in pots as an alternative of straight in the floor).
Now semi-retired, she and a group run the small farm peppered with avocado and citrus bushes and adorned with quirky customized yard artwork. They additionally supply excursions throughout open hours so guests can study somewhat one thing about luffa.
Guests saunter by way of a steamy greenhouse where lengthy inexperienced gourds that resemble zucchini dangle from trellises in spectacular portions. They study that whereas some Asian cultures increase smaller varieties which might be inexperienced, tender, and edible when younger, it’s not widespread as a culinary ingredient in the U.S. And after they inquire about why crispy brown gourds are nonetheless hanging on the vine, they study that luffa isn’t harvested till effectively after you suppose it’s lifeless. “When it’s completely brown and dry we cut it off the vine,” Gamble explains.
Only then, and after it’s peeled, will it lastly be recognizable as the fibrous exfoliating sponge many know and love.
It’s what’s on the inside that issues
Getting to that time, nevertheless, takes time and distinctive organic features that aren’t seen to the bare eye. It takes six to 9 months after planting luffa seeds for them to be prepared to harvest, Gamble explains (longer in winter, shorter in summer time). It takes three to 4 months only for slim inexperienced child gourds to begin sprouting from reaching vines and the male flowers, that are obligatory for pollination, to bloom.
Once that occurs and pollination is full, the squash are technically edible and ripe for selecting. The inside fruit tends to be slimy like okra, so it’s a little bit of an acquired style. However, there are definitely recipes from round the world that incorporate this dietary veggie.
But The Luffa Farm isn’t in the enterprise of unpopular produce, so the fruit is left on the vine where it might probably grow as massive and heavy as the trellised vines can deal with, Gamble continues. As that occurs, the inside plant fibers act as the veins that feed water and vitamins to the seeds, the care of which is the plant’s primary directive. Those veins get thicker and denser to nourish the seeds as the gourd grows.
When the gourd will get too massive—about the measurement of an outsized zucchini—the vine, which might grow 30 to 40 toes in any course, cuts off the water provide to the entire fruit so as to redistribute assets to different vegetation on the vine which might be nonetheless rising. “As the vine sucks the water out and recycles it, [the gourd] dries up,” Gamble describes. When that occurs, as an alternative of rotting like most different produce, the luffa turns from deep inexperienced to yellow to brown and exhausting.
When that occurs, the gourd feels mild as air as a result of all the liquid and vegetable matter has dried up, leaving solely a fibrous community of cellulose inside the now-hard, shell-like pores and skin. That’s when it’s time to harvest. The pores and skin is cracked open and the seeds, which could be replanted, are shaken out. Harvesters soak the entire gourd in water for 5 minutes, which rehydrates the skinny layer of vegetable residue on the underside after which “the skin so it slides right off,” Gamble says.
What’s left over is an ethereal, mild, sponge-like spidery community of plant fibers that make a wonderful pure multi-purpose sponge that’s pliable when dry and even softer when moist. That’s what makes it such a lovely choice amongst skincare fans.
Not all luffa are created equal
If that doesn’t sound in any respect like the inflexible, compressed luffa you see on the market at your native well being meals retailer, you’re not unsuitable. Most luffa are imported, and since they’re a plant, they should be handled beforehand to guarantee they received’t transport bugs, illness, or different agricultural blights, Gamble explains.
“Those heat treatments in particular are what damage the fibers,” she states. It shrinks the in any other case mild and free cellulose constructions and makes the luffa exhausting, compact, and fewer pliable. Compromising the construction additionally makes them extra susceptible to bacterial progress, as a result of they don’t dry out as simply or utterly between makes use of.
Luffa grown in the U.S., like the ones from The Luffa Farm, don’t have to be handled with something since they’re not imported from abroad. They simply get a fast rinse earlier than they’re bought. As a consequence, they’re softer, extra nice on pores and skin, extra versatile, and longer lasting. One may final up to a 12 months of standard use. Plus, as a result of they’re extremely porous, “they don’t create the same breeding ground for bacteria,” Gamble provides.
A plant with limitless makes use of
But exfoliating isn’t all these vegetation are good for. On the opposite, Gamble says there are various makes use of for luffa. Softer varieties can be utilized as a facial sponge rather than a washcloth. They may even be tossed in the washer for a deep clear, although it’s best to keep away from placing them in the dryer. They make glorious dish sponges and pot scrubbers. Gamble makes use of one on her chrome steel range.
A moist luffa makes fast work of washing your automobile, too, particularly when it comes to scrubbing bugs off your grill, Gamble recommends. The fibers received’t even scratch the end. They’ve even been used as insulation in mud brick homes and as industrial filters and should have impressed a sunlight-powered porous hydrogel that might probably purify water. The better part: untreated luffa sponges are compostable, making them an eco-friendly different to artificial sponges.
“They are so unique as a plant,” Gamble says, a really multifunctional and sustainable pure product whose makes use of go far past bathtub time exfoliation. And sure, it’s one which grows on land, not underwater.
