Japanese knotweed, a plant that causes billions of dollars of damage each year. It’s listed as one of the most destructive invasive species in the world. It was brought to our country by gardeners who appreciated its bamboo like beauty. It’s an edible plant that has high concentrations of the antiaging polyphenol called resveratrol. I’m really at the tail end of being able to harvest the plant. In a week the stalks will become too woody to eat. I plan to kraut and pickle them. As always, be careful not to forage in contaminated soil.
