LOL. I -love- this!

So I've always told my kids that "plants" (in the gardening sense) are the ones we choose to have in our garden, and weeds are the ones we don't. It's totally arbitrary (which it is). Except I am not a particularly assiduous weeder of my planting beds. Which I think is why their idea of which species are weeds is very unlikely to line up with that of any habitue of a garden center!
