Marigolds

My yard, and one flowerbed in particular, has been more colorful this year. As someone who prefers to cultivate native plants, partly because the deer who wander into the yard don't eat them as readily, I have garden phlox and purple coneflowers growing in the front flowerbed. I also found some volunteer black-eyed susans growing elsewhere in the yard and transplanted them into the front flowerbed. It takes a lot of water, surprisingly, to keep these black-eyed susans from drooping. 

Recently, I discovered what my Search by Image app refers to as field marigolds growing in the front flowerbed. My wife's sister says that her app refers to them as tree marigolds. I don't know where these flowers have come from. I am hoping that I can get their seeds to grow so that there will be even more growing next year. Even though today is the autumnal equinox, some of the blooms have yet to open.

The pictures appearing below capture these field marigolds/tree marigolds.
