Long overdue.
Hardly remember WHEN I first saw it in the crack by the wall - I may yet find earlier snaps
than the above, from November last year.
It's just an escape from the nearby flower bed, of course
-as seen in the picture from May 2002, when there was such big and beautiful Garlic Mustard there.
But it's been so incredibly optimistic
coming back after several forceful weedings down to ground level
scooping the crack out - even once the use of acetic acid
or some other corrosive stuff.

However after spring cleaning 2005 it is gone.
