Trillium grandiflorum was the first to bloom.
Followed by Trillium catesbaei that was located in another patch a bit further down the stream.
Now there are three Trillium species. So far. I had seen this group before. It looked like it had no flower buds and was not going to bloom. Looking closer today I saw some buds and then found the flowers hiding under the leaves.
I pulled the flowers up to the top of the leaves to get their picture.
Trillium number three, Trillium cernuum, the Nodding Trillium.
