A continuation from this post.
First, I found this really nice website that has pictures of flowers. I was able to identify some that weren’t in my book using it.
Partridge pea — this made me really excited. It’s a very beautiful yellow flower, and it has taken over the area where the yellow whorled-leaf coreopsis was earlier blooming. It was so pretty and so profuse that I feared it was invasive; and also it wasn’t in my book. But then I found it online. It is native to this area.

Asiastic dayflower — from the name, you can kind of tell this flower is really from Asia. So it’s not native. It was nestled in with the partridge pea. The flower blooms for one single day. I didn’t know I was looking at something so fleeting until later. It was not in my book, but it only has two blue petals atop a yellow fuzz, so it was easy to search for.
I found this string of light purple flowers … and they kind of look like the ‘everlasting pea’, but I don’t think that’s actually it. I saw them two days ago, nestled in among the partridge pea; and today it’s gone!
Same with these small white flowers spreading out of a bell shape: so pretty, but I’m not sure what they’re called either.
