Almost at the same stage as the red Trilliums were the yellow ones

 I found these right where Vicki said they were . she noticed them the past 2 years. They appear when the reds appear - so a couple of days before the more traditional white Trilliums of this area.

The tree in the first photo left side, is the same one in the bottom photo right side. I have moved about a meter to the left between photos.
