Calycadenia fremontii is a type of flowering plant. It is often called Frémont's western rosinweed. This name comes from John C. Frémont, a famous explorer. This plant belongs to the daisy family, which includes sunflowers and dandelions.

This plant grows naturally in parts of southwestern Oregon and northern California. You can find it in places like Josephine and Jackson Counties in Oregon. In California, it is mostly found north of Napa and Placer Counties. There are also a few small groups in Santa Clara and Tuolumne Counties.

Frémont's western rosinweed is common in many different places. It grows in mountains, foothills, and valleys. This plant is an annual, which means it completes its whole life cycle in just one year.

What Frémont's Western Rosinweed Looks Like

This plant can look different depending on where it grows. It usually has a stiff, upright stem that is covered in hairs. The stem can grow anywhere from 10 centimeters (about 4 inches) to one meter (about 40 inches) tall.

Leaves and Flowers

The leaves are long and thin. They grow in an alternate pattern along the stem, especially near the bottom. The longest leaves can be up to 8 centimeters (about 3 inches) long.

The plant produces one or more flower clusters. These clusters are called flower heads. Each flower head has special glands that can feel sticky.

Each flower head has 2 to 6 ray florets. These are like the "petals" you see on a daisy. They can be white, red, or yellow. In the center of the flower head, there are up to 20 disc florets. These are the tiny flowers that make up the center part.

Seeds and Reproduction

The fruit of the plant is a type of seed called an achene. Achenes from the disc florets might have a pappus. A pappus is a feathery or scaly structure that helps the seeds float away in the wind.
