I, finally, did it.

I watched get slowly worse; all the while wondering why.  I finally got around to looking.  It had been snapped, at a joint.  I have NO idea when/how it happened.  I do remember tripping and falling once yonks ago - BUT:-
1. While it was in this part of the front garden.
2. a) It was inti the Daphne, not Choisya Ternata - Sundance. 
2. b) It was a good 2 yds/mtr from this point.
3. None of the Daphne died.
However/whenever doesn't really matter but photogenically I suspect it does.  Consequently it's no linger there.
