Weed

a plant that is not valued where it is growing and is usually of vigorous growth; especially one that tends to overgrow or choke out more desirable plants ...

raises all kinds of issues:
1. define desirable
2. valued is such a relative thing
3. when does vigorous become overgrowth
4.
5.

thanks for the comments on yesterday's - the guy dresses in an old time way so nostalgic treatment did seem the right way to go.
