How Do You Quell An Invasion? You Eat It!   6 comments

You’ve seen it, wondered what it is, possibly, even cursed it; but, have you tasted Japanese Knotweed?  If you haven’t, please do so, quickly; because this terribly invasive species is delicious, and nutritious. Like most wild edibles, the Japanese Knotweed window of opportunity is brief and fleeting, swiftly (April – May).

Maybe, if we all ate Japanese Knotweed, it wouldn’t be so invasive!  To make Knot sauce, chop the young stalks (6-10 inches tall) into 1 inch pieces and boil them for about 4 minutes, until tender.  Drain, slip the rind off the larger pieces, mash and chill.  Knot sauce can be sweetened to individual taste; with a drizzle of honey or molasses.  It’s great over a scoop of good vanilla ice cream; and I love it in my morning smoothie.  Or, spice it up for savory delights.

Japanese knotweed, Polygonum cuspidatum, a member of the Polygonaceae family,  has hollow stems with distinct raised nodes.  It’s easy to find new growth, just look for last years old dead remains (which still stand, up to 12 or 13 feet high); and look down!  You will see chunky green stems, flecked with red, topped in red, with tiny red and green leaf buds.

 The spade shaped leaves are broad, ovalish, and pointed on the ends, with a truncated base.

This week I’m going to try  Blanche Cybele Derby’s Dandy-Knot muffin recipe; found in her DVD “Edible plants: Wild + Tame” (Spring).  (see link below)

You may even substitute cooked knotweed, which gets very soft, for lemon juice, transforming familiar recipes into exotic ones. Or use a chopstick to pierce the membranes that separate the segments of 1-foot-tall shoots, peel, stuff the stalks with sweet or savory stuffing, and bake in an appropriate sauce.

Caution should be taken when eating Japanese Knotweed, as it contains oxalic acid, which can aggravate conditions such as arthritis, gout, hyperacidity, kidney stones and rheumatism.  

Thanx for stopping by.  See you soon.

  1. It’s great your spreading the word on what you can do with this species. If more people ate it maybe there would be less of an invasion here in the UK – but be careful not to spread it. You really don’t want this stuff growing on your property.
