Here is a "regular" Trout Lily with a White Trout Lily nearby. As you can see, they are essentially the same, except for the colour of their flowers.
The two species generally like the same habitat. However, the White Trout Lily is much less common than the yellow species.
A partially opened flower. Very "graceful" looking.
