I figured out the name of the sedum Christie was inquiring about, it is either Neon or Pink Neon Sedum.
opps, I wish I could change the name of this post, this is Yarrow not Sedum, sorry about that. The post title should be Yarrow with a Monarch, can't remember the name of the yarrow.
I didn't even notice that it was yarrow instead of sedum when I looked at your photo. lol I was just thinking that the color looked different from mine. I will try to post some photos of my sedum.
