The Gutierrezia petradoria is a type of flowering plant. It belongs to the Asteraceae family, which includes daisies and sunflowers. People often call this plant the San Pedro snakeweed or goldenrod snakeweed.

Where Does it Grow?

This special plant grows only in western Utah in the Southwestern United States. This means it is endemic to that area. You can find it near the lower Sevier River watershed. This area is mostly in Juab County and Millard County.

What Does it Look Like?

The Gutierrezia petradoria is a plant that lives for many years. It can be a soft herb or a small, woody subshrub. It usually grows up to 40 cm (16 in) tall.

Each branch of the plant ends with one or a few flower heads. These flower heads are bigger than those on most other plants in the Gutierrezia group. Each head has 5 to 13 small disc florets in the middle. Around the edge, there are 4 to 10 bright yellow ray florets. These ray flowers can be up to 10 mm (0.39 in) long. They are much larger and more colorful than the ray flowers on other plants in this genus.
