How often do you stop to admire weeds?
I've been busy pulling weeds to put in a garden at our new rental house, and boy, are there a ton. Some are really awful, like the pricklies you have to pull just right or else you have stickers jabbed in your fingers.
But some, like these, are actually quite pretty. I'm not sure what they are, but I just had to snap a few pictures before I pulled them and sent them to the great dumpster in the sky.
Really, weeds are just plants that are well-adapted to their environment.
If they weren't going to suck up all the water and nutrients away from my fruits and veggies, I'd let them stay.
