Discovering the Trans-Pecos Thimblehead Plant

Where Does This Plant Grow?

The Trans-Pecos thimblehead plant is found in the southwestern United States. You can see it in far western Texas, Arizona, and New Mexico. It also grows in northwestern Mexico. This includes areas like Baja California, Sonora, and Chihuahua.

What Does the Thimblehead Look Like?

Hymenothrix wislizeni is an annual herb. This means it completes its entire life cycle in one growing season. It can grow up to 70 cm (28 in) tall. That's about as tall as a large ruler!

Each flower head on the plant is quite interesting. It has between 15 and 30 disc flowers in the center. These are usually yellow or cream-colored. Around these central flowers, you will find 8 to 12 ray flowers. These ray flowers look like petals and are typically yellow.
