It's Dandelawns when dandelions prevail.

I'm thinking of dandelions.  Why do people spend so much time and energy trying to kill them and get them out of their lawns.  Who said lawns have to be 100% green, and the cost to keep that perfect green could amount to quite a bit of money.  So, why not let the dandelions take over.  They seem happy to take over your lawn and for free at that.  And what is the difference to you and your neighbors anyway?.  Besides, if you get hungry you can grab few dandelions and have them for lunch :p
Well, the other difference is color.  Your lawn would reflect a very bright yellow with some dark green which would actually bring out the yellow.  A yellow and green lawn.  I love it.  Let them dandelions prosper and multiply.  Dandelions, they're not a weed anymore, they are dandelawns.
