Lawns are green where I live in Virginia. Many folks work very hard at keeping their green spaces weed free. Countless well manicured neighborhoods pay herbicide companies to lay down fertilizers and weed killers. Virginia lawn services busily mix-up and spread the “death cocktails” for the eradication of the clover and dandelions.
Please note the protective mesh that surrounds the dandelions in the lush gardens at Blarney Castle, Ireland. No lawnmower is going to mow these beauties down and no polluting herbicides are taking them out of the natural environment. 
Label them a weed.
Refer to them as a flower.
I go with flower.
