This flower popped up in my yard and I think it may have escaped from my neighbor's yard. She buys those pack of wild flowers from Walgreens and tosses the seeds around. The day I noticed this flower I was going to toss it but out of nowhere a large humming bird moth appeared in the yard and started feeding from it. I'd never seen one of them before and I was surprised by how fearless the insect was as it landed and probed all the blooms on the stalk.
