An exception

Here's something we can all hate on.



An easy target.. perhaps. 

But in the western US, noxious weeds in our rangelands and native habitats are a scourge upon the earth. Truly.

Scotch thistle (Onopordum acanthium), for example. Bees love thistles and most native thistles are lovely and should be tolerated wherever possible... 

BUT. Scotch thistle should die a fiery death. Here's the difference:
