One of my favourite salad greens/green smoothie ingredients is Nipplewort. It is also delightfully called Irish Wildflowers.
I don’t hear this edible weed mentioned much. Could be something to do with the name! 🙂
Here is one place nipplewort show ups as an important plant – ‘Nanakusa no Sekku’ day in Japan. Japanese traditionally have porridge of seven edible spring herbs on January 7th every year – water dropwort, shepherd’s purse, cudweed, chickweed, nipplewort, turnip and radish.
