Enjoy Your Wildflowers
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.
Celebrating Wildflowers periodically features a different wildflower plant found on our national forests and grasslands.
The Plant of the Week descriptions are organized alphabetically by genus and species.
