It was a big disappointment to see huge masses of garlic mustard appearing in a section of the old field. I think the abundance of this species this year, demonstrates just how resilient this plant is, and how resilient many invasives are. At this particular site, garlic mustard was dug up by the root about 5 years ago. The following year there was none, the year after there was a reappearance and masses of the stuff was pulled out by the roots and bagged for disposal. In the early summer of 2012, the site was rototilled in an effort to get rid of both lamium (next photo), and garlic mustard. Last year, there was no sign of either species, this year, both are vigorously growing.
