What the Oregon Western Rosinweed Looks Like

The Oregon western rosinweed is an annual herb. This means it grows from a seed, flowers, produces seeds, and then dies all within one year. It grows a straight, reddish stem that can be very tall. Sometimes, it can grow over 3 feet (100 centimeters) high.

Leaves and Stems

The leaves of this plant are long and very narrow. They can grow up to about 4 inches (10 centimeters) long. The plant's stem has special spots called nodes. These are the places where leaves or branches grow out.

Flowers and Seeds

The plant produces one or more flower heads. These flower heads grow at different nodes along the stem. Small, leaf-like parts called bracts surround the flower heads. These bracts have sticky resin glands on their tips. These glands produce a sticky substance.

The flower heads themselves are a bit hairy. In the center, they have many small disc florets that are purple at their tips. Around the center, there are a few yellow ray florets. These are the parts that look like petals on a daisy. After the flowers bloom, the plant produces a type of fruit called an achene. An achene is a small, dry fruit that contains a single seed, like a sunflower seed.
