An article published in Compass Travel Vietnam caught us by surprise. Of all things, water hyacinth fetches a high price in some places. "Hyacinth is a plant that lives in abundance, growing wild in ponds and lakes in rural areas. But when it is sold online, it costs up to 50,000 VND / plant, even in Japan, water hyacinth is also packaged and sold by the plant.($1=24,000 VND)" As you know, water hyacinth is a cursed invasive species in U.S. waters. Much dinero has been spent trying to eradicate it. But what if we just ate the weeds?
