Plant Identification … Anyone?

I have a few apps that sometimes help me identify flowers and other plants. They also, on occasion, misidentify so I always have to verify the results. Sadly the apps have no “error box” to allow us to notify them when they’ve got it wrong.

So far this plant, though, has me (and the apps) stumped. I should know it, I’m sure. It’s right on the tip of my tongue … maybe. Sort of. Or not.

Perhaps there’s a botanist out there who can help me out. If not I’ll turn to the Flickr group “What plant is that?” But here’s someone’s chance to shine … give me a name please!

(Yarrow comes to mind, but I just don’t think so ….)
