Collinsonia canadensis and Campanulastrum americanum. This post was edited by carol23 on Sun, Sep 22, 13 at 21:55

Looks like Persicaria pensylvanica. The name you were probably thinking of is lady's thumb, which is Persicaria vulgaris. It's possible it is that species but that usually has chevrons on the leaves.

I looked up Scarlet Flax on Google and that is DEFINITELY the hot pink flower that is growing amongst my wildflowers. Thank you so much for the help IDing it.. I wouldn't have figured it out otherwise. I had researched "pink wildflower with 5 petals" a hundred times in different words, but couldn't find anything accurate. Apparently it's considered red, but to me.. it's hot pink! Also, thank you for help IDing the Calendula.. I thought it might be Calendula (buds and foliage looked familiar), since I do have a few of those in my front gardens.. but the ones in my front yard are only yellow. I wasn't sure they came in orange (with brown centers), too. Last year I bought 6 Calendula seedlings.. they reseeded and now there's about 50 in my front yard!! The one in my original posting must've been from seed, included in one of the wildflower packets I purchased and planted.. since it is a different variety. Wasn't sure it was a wildflower.. Glad to know!! Thank you again for your help.. Always appreciated :)

Hi Megan, if you haven't done so already, try posting this in the Name That Plant! forum. It gets a lot more traffic, and they really know their stuff there.
