Pulling wayward lilies of the valley out of the lawn reminds me that a weed is commonly defined as any plant in the wrong location.
Some plants, though, I just can't consider to be weeds. Ever. The pristine blossoms of star-of-Bethlehem Ornithogalum umbellatum give it a free ride where ever it wants to go. Even smack dab in the middle of the lawn is perfectly okay.
Same goes for woodland phlox, jack-in-the-pulpit, and mayflower.
On the other hand, Japanese knotweed Polygonum cuspidatum is never welcome, any time or any place. After almost two years of battling this beast, I have practically eradicated all vestiges along the side property line. And, I am proud to say, without the assistance of herbicides--all natural, hand-pulled goodness. A few weak shoots poke up every few days, but nothing that can't be corrected by a gentle tug.
So I am happily too late to take advantage of these Japanese knotweed recipes offered by the New England Wild Flower Society
