I planted a couple of rows of sunflowers in my garden a while back. There are dozens if not hundreds of varieties.

If that field has ever had hybrid sunflowers planted, these might be the natural offspring of spilled seeds. They won't look anything like what the farmer planted on purpose.

You'd be surprised how far they can spread too, over time, and with the help of various critters. But somehow I don't think any of the cherry pits I spit out the window last week will ever sprout. I was on the highway.
