As I was on my search and destroy mission against the garlic mustard enemy, I found a jack-in-the-pulpit. I had found one several years ago in the northwest corner of the woods, but this was the first time I saw one in the southeast corner.
This is a trillium,trillium sessile, commonly called toadshade today but known as wake robin a hundred years ago. This is the first time I've seen it in the woods. It is clump forming and I am pleased to see two plants in my emerging clump.
Of course, this trillium, trillium grandiflora, is becoming abundant. It is so exciting to spot one in a new place in our little woods.
This is known as lady's thumb. I heard a story about the "bloody" thumbprint and tried to find it online to no avail. She pricked her finger was one version and another version as she murdered her husband and left evidence on this little plant. Online I found a Scottish tale about the plant was at the foot of the cross. Or you can make up your own story!
The mayapple patches are spreading. Steve and I wondered about the two distinct shapes in this patch. 
And this is my unknown but distinctive plant. The stems are a glaucous blue. No flowers yet. I'll have to keep monitoring it.
