OK, what's that green stuff in Poplar?

An experiment gone wrong. *Somebody grafted some output from the Treasury's
Bureau of Printing on to a sapling, to attempt to disprove the "poplar
adage" that 'money doesn't grrow on trees.' *Seems like the coloration
'took', but the patterns were distored beyond recognition.

Actually, the green patine is formed by a poplar tree growing next to
other vegetation, like the kind that can climb walls. It makes a
poplar green with ivy.
