The Wyoming paintbrush (scientific name: Castilleja linariifolia) is a beautiful perennial plant. This means it lives for more than two years. It grows naturally in the United States and is famous for being the official state flower of Wyoming. People also call it the Wyoming paintedcup or Wyoming Indian paintbrush.

Discover the Wyoming Paintbrush Flower
The Wyoming paintbrush is a perennial plant, meaning it comes back year after year. It usually grows between 18 and 100 centimeters tall. Sometimes, it can even reach up to 2 meters, which is taller than most other paintbrush flowers.
What Does the Wyoming Paintbrush Look Like?
Stems and Leaves
Each plant has several stems that grow straight up or lean slightly. These stems often branch out near the top. The lower parts of the stems can be smooth or covered in tiny, soft hairs. Closer to the flowers, the stems might have bristly or long, soft hairs.
Underground, the plant has a strong, woody base called a caudex. This sits on top of its deep taproot, which helps it find water.
The leaves of the Wyoming paintbrush are usually gray-green or yellowish. Sometimes, they can even have a purple tint. They are typically 1 to 10 centimeters long. Most leaves have smooth edges, but some higher up might have narrow side parts, like small fingers. These leaves are often thin and look like grass or threads. They can also be a narrow lanceolate shape, like a spear tip. The leaves are usually smooth, but can sometimes be hairy. They are not thick and juicy, but their edges might be a bit firm and curl inwards.
Beautiful Blooms
The top 4 to 20 centimeters of the stem hold the plant's amazing flowers. These flowers form a cluster that is 2 to 7.5 centimeters wide. The flowers are arranged in a spike-like shape, with each flower attached directly to the main stem. Botanist Francis Marion Ownbey once called this "our most spectacular species of Castilleja."
The actual flowers are partly hidden by colorful leaf-like structures called bracts and the fused sepals, known as the calyces. The bracts are usually bright red or red-orange. However, they can also be pale green, yellow, magenta, pink-purple, or white. Sometimes, they are pale green or yellow at the bottom and then change to another color. Each bract often has one or two pairs of side lobes that spread out or point upwards.
The calyces are usually longer than the bracts, typically 1.8 to 3 centimeters long. Their bases are greenish, whitish, or yellowish, matching the color of the bracts above. The inner part of the flower is shaped like a curved tube, about 2.5 to 4.5 centimeters long. These inner parts are usually yellow-green or green. You can see these flowers blooming from as early as April to as late as October, depending on the area.
After blooming, the plant produces small fruits called capsules. These are about 9 to 13 millimeters long.
You can tell the Wyoming paintbrush apart from the giant red paintbrush by looking at the cut on the front of its fused sepals, which is 1.2 to 2.2 centimeters long.
How Was the Wyoming Paintbrush Named?

The Wyoming paintbrush received its scientific name, Castilleja linariifolia, in 1846. It was named by a scientist named George Bentham. He described it in Latin, noting its unique features. The first sample of this plant used for scientific study was collected by John C. Frémont in August 1842. This sample came from the Laramie Mountains in Wyoming.
This plant belongs to the genus Castilleja, which is a group of similar plants. It is part of the plant family called Orobanchaceae. Sometimes, different scientific names were given to the same plant over time. Scientists now agree on Castilleja linariifolia as the correct name.
Interestingly, a rare plant called Castilleja christii grew from a mix of the Wyoming paintbrush and the giant red paintbrush. Even though both parent plants are usually red, C. christii has yellow or yellow-orange flowers.
Other Names for This Flower
The scientific name linariifolia comes from Latin. It means "with leaves like toadflax," referring to the plant's narrow, grass-like leaves.
Most people know this plant as the Wyoming paintbrush. It also has other common names like Wyoming paintedcup or Wyoming Indian paintbrush. Sometimes, it's called the long-leaf paintbrush or narrow-leaved paintbrush. In the Hopi language, it is known as pala'mansi, which means "red flower."
Where Does the Wyoming Paintbrush Grow?
The Wyoming paintbrush grows naturally across many western states in the US. You can find it from the Rocky Mountains all the way to the Pacific Ocean, but not in Washington state. It also grows in the state of Sonora in northwest Mexico.
In Wyoming, it is common in most parts of the state. It also thrives in southern Idaho, southeastern Oregon, and many areas of California. You can find it in every county in Nevada and Utah. In Colorado, it grows throughout the western half of the state.
This plant can grow in many different places, from low elevations of 600 meters to high mountains at 3400 meters. It likes dry, rocky slopes, open plains, and forest clearings. It is often found in sagebrush steppes, grasslands, and pinyon–juniper woodlands.
Who Visits the Wyoming Paintbrush?
The Wyoming paintbrush is a very important food source for some animals. For example, the Edith's checkerspot butterfly (Euphydryas editha) loves this plant. In places like Gunnison County, Colorado, these butterflies eat almost only the Wyoming paintbrush.
Even though other plants like the desert paintbrush offer similar food, the Wyoming paintbrush is often more available. This is especially true during dry times. Because of this, the butterfly has learned to prefer the Wyoming paintbrush for its meals.

Wyoming's State Flower
The Wyoming paintbrush holds a special place in the state of Wyoming. When people were choosing a state flower, Dr. Grace Raymond Hebard from the University of Wyoming strongly supported this plant. She believed it was a better choice than other flowers like the columbine.
However, not everyone agreed. Professor Aven Nelson, another botanist, thought it might be hard for people to tell different paintbrush species apart. He also noted that it was a parasitic plant, meaning it gets some nutrients from other plants. This made it harder to grow in gardens, unlike popular state flowers such as the Colorado columbine.
Despite these concerns, the State of Wyoming officially chose the Indian paintbrush (Castilleja linariifolia) as its state flower. This happened on January 31, 1917.
Art and Traditional Uses
The seeds of the Wyoming paintbrush are sometimes included in wildflower mixes. These are sold for planting in the southwestern United States. However, trying to move paintbrush plants from the wild to a garden is usually not successful.
Among the Tewa people from Hano in Arizona, the red flowers of this plant are often used in art. They paint them on pottery, carve them into wood, and even create them with colored yarn. Some Shoshone people, interviewed in Nevada during the 1930s, used the plant in their traditional medicine. They would boil the roots in water and drink small amounts over time. It was also thought to help 'purify' the blood, cause vomiting, and serve as a general medicine for various health issues.
