Not Weed?

Like Locro de Papa, this potato soup fog couldn't be creamier if they pureed the sunshine. I miss that Andean treat topped with avocado slices. Even the dead droughty corn stalks look soft this morning as i'm transported a continent away.
Yesterday i was stuck in traffic approaching an overpass in our local concrete jungle and my olfactory sensibilities were awakened from their depressed state by a heavenly aroma. Leaning out the window of the old white beast, i closed my eyes and inhaled again.
Leaves scritch against each other, bees forage, and garbage rustles along the pavement imitating windblown forest litter.
The messenger? One of those noxious invasive species of plants once thought to be ornamental or useful. Imported back when people didn't know better, of course. Japanese knotweed (Fallopia japonica) blossoms smell nice even when you're not among a line of commuters belching the nitrates it probably enjoys.
If you find this friend growing along a stream that has only animals fouling it (no industrial or pesticide runnoff, and not within fifty feet of a road) pluck a tender shoot and take a bite. With a zing like sourgrass/heart clover/wood sorrel that takes you back to a nice moment in childhood, this one is much more substantial so you can make salads comprising lemon juice, salt, grape tomatoes, avocado pear, feta cheese, black walnut crumbs, whatever. If you're really blessed, like some disgruntled gardeners i know, it will burst energetically through your vegetable patch, and you will now know what to do with that foreigner whose smooth pale roots reach clear through the earth to their native Asia: Feast!
Then again, if you are more pharmacologically inclined, you could refine and sell Resveratrol to your neighbors, and make sure they don't pronounce it as though it has the word 'reserve' in it.
