I got to spend some time in the garden today and look what I found dropped the other side of the garden gate.
It appears that the fox carried it around for a bit before deciding it wasn't edible. Amy commented on the last post asking why foxes would take plants, and I have no idea. I would guess that the digging up is to get at worms, but why they would take plants, or even just carry them in their mouths for a bit is a total mystery. Maybe it got spoked and ran off before it could drop the plant.
So while the plant is not quite what it was, at least the two largest are still around and stand some chance of surviving to form new clumps.
