Plant of the Week

Thousands of wildflowers grow on our national forests and grasslands, in many shapes, sizes, and colors. A field of wildflowers or colorful plants upon a lush forest floor is a beautiful sight, but so is a single flower or scattered plants growing upon what at first glance may appear to be a dry and desolate landscape.

Each week Celebrating Wildflowers features a different wildflower found on our national forests and grasslands. Enjoy them here as well as throughout Celebrating Wildflowers.

The Plant of the Week descriptions are organized alphabetically by genus and species:
