They haven’t actually started popping up in my yard yet, but I’ve seen them in the lawns of people who live closer to town, where all the flowers are about a week or so ahead of mine. I used to fight it, but now I embrace the dandelions.
(BTW, clicking through on either of the above pictures will load a VERY large file, wherein you can see pollen on the yellow dandelion. It’s pretty awesome-looking, if I do say so myself. Which I do, apparently.)
