The Eriophyllum lanatum, also known as the common woolly sunflower or Oregon sunshine, is a bright yellow plant. It is a common flower found across North America and belongs to the sunflower family.

Discovering the Woolly Sunflower

This plant was first seen by the famous Lewis and Clark Expedition. They spotted it growing near their camp on the Clearwater River in what is now Kamiah, Idaho. On June 6, 1806, they collected two samples of this plant.

Later, a botanist named Frederick Traugott Pursh studied the plants from the expedition. He gave the woolly sunflower its first scientific name, Actinella lanata, in his 1813 book. The name "woolly sunflower" is often used for any plant in the Eriophyllum group.

Where Does the Woolly Sunflower Grow?

The Eriophyllum lanatum is native to western North America. It loves sunny, dry places that are less than 10,000 feet (3,000 meters) high. This plant grows best in full sun and well-drained soil. You can also find it on rocky hillsides.

It is very common in California. There, it grows in chaparral areas, oak forests, and pine forests. It also thrives in grassland and sagebrush scrub habitats.

You can find it north through Oregon into British Columbia. It also grows east through Idaho into Wyoming, and through Nevada into Utah. Its range even reaches south into Baja California in Mexico.

What Does the Woolly Sunflower Look Like?

The woolly sunflower is a perennial herb. This means it lives for more than two years. It usually grows to be about 1 to 2 feet (30 to 60 centimeters) tall. The plant often grows in bushy clumps with many branches.

Both the stems and leaves can be covered in soft, gray, woolly hairs. These hairs help the plant save water by reflecting heat. They also slow down air movement around the leaves. This gives the plant a dusty gray color.

The leaves on the upper stems are long and thin. The leaves lower down on the plant have deep cuts, making them look like feathers.

Its Bright Yellow Flowers

The flowers are bright yellow and look a lot like true sunflowers. They can grow up to 2 inches (5 cm) wide. Both the outer ray flowers and the inner disk flowers are yellow. Each flowering stem usually has one flower head.

These cheerful flowers bloom from May to August.
