Tuffet

I'm not sure what the correct expression is, for a bit of random greenery that sprouts up from some ancient stonework. A tuffet, considering that Ms Muffet sat on one, may have been more substantial. This was just a bit of random vegetation that caught my eye as I scampered down through the remains of the Newcastle - maybe it's just a tuft. But hurray, it seems to come back every year, on these stones which have been there for 800 + years.
