Most things with weed in the name is going to be easy to grow. A lot of people with aquariums or ponds feel plagued by it. I love it for aquariums it's one of the few things that can out compete algae

Youtube has sent me down the rabbit hole. Almost every common weed that's not native to North America was once a staple food crop in Europe.

But in the mid 20th century big agriculture realized they'd make more money selling annuals, fertilizer, and pesticides... instead of letting people grow perennial plants that solved those problems on their own.

Just watched a lady "grow" it in buckets of pond/tap water. It doubles in biomass every 48h. Literally just let it sit there.
