Japanese Knotweed: A Healthy Edible Invasive

Japanese knotweed has a short 3-week growing season, but it can be frozen raw and used all year. If you like the taste of rhubarb, you'll enjoy knotweed. For more information about the best way to harvest knotweed, check out my e-book Joyful Foraging: Learn How to Feast on the Food Growing All Around You. Field garlic and garlic mustard, additional recipe ingredients, are also covered in this e-book.

One of the challenges of our virtual world, is that I never know who is really trying to find me. Before I launched, I was A huge shout out to Carly Leusner for crediting me for this knotweed recipe, even when I was in a state of metamorphosis.

Carly, if you're still around, Joe is a fellow member of the Connecticut Westchester Mycological Association. I'm reintroducing the chicken mushroom ingredient, which was part of Joe's original recipe:


4 Cups Cleaned/peeled Japanese knotweed
2 TBS Honey or agave
3 TBS Tamari or soy sauce
6-12 Field garlic leaves and bulbs (pull up a large clump)

6-8 Garlic mustard flower clusters for garnish

1. Japanese knotweed
2. Chicken of the woods mushroom
3. Field garlic
4. Garlic mustard top leaves and flower
5. Violet flowers

1. Garlic
2. Ginger
3. Carrot
4. Sesame oil

1. Honey
2. Tamari or soy sauce

Choose knotweed stalks that are flexible, no thicker than young asparagus stalks.
Trim leaves from stalks and gather enough to fill a paper grocery bag
That should yield about 4 cups

If you are lucky enough to find fresh chicken mushroom, and/or field garlic harvest them both.
Keep an eye out for garlic mustard leaves and flowers and for violet flowers - both for plating and garnish

When I took this photo, I had hit the forager's lottery also finding wild ramp leaves. I made rice and served this as a main dish, instead of a side dish. Knotweed can be savory or sweet, as in this recipe for knotweed compote.
