Seeing this thread has just reminded me that I still have this picture of
an ivy-covered GEC Z8896 on a concrete column in Birchington-on-Sea in Kent that I took 5 years ago. Sadly the column has now been replaced with a
totally characterless and ivy-less Mini Iridium, but it was a lovely sight while it lasted!
I've also got this pic of an
SGS203 on a 1967 S&L column which has a tree growing up its shaft on London Road in Romford, Havering. This is still surviving in 2013, but has escaped replacement by a whisker, as the rest of the road has had its lanterns swapped for
Airtraces. The SGS203 is just behind the camera in the Streetview. As you can see, the tree has now covered the entire shaft (including the bracket joint) so it looks as if the SGS203 is installed on a bracket attached to a tree!
I recall seeing an ivy covered, swan necked, cast iron column with a T/E Beta 5 when I use to do a paper round. It was dayburning, but because of the ivy, the council couldn't gain access to the control box. Eventually the ivy was removed as one of the residents burnt some of it off, probably as it was affecting their nearby wall.
The column has probably been replaced now.That's actually a Philips XGS103!
