Coreopsis douglasii is a type of flowering plant in the daisy family. It is often called Douglas' tickseed. This plant grows naturally in California, from Santa Clara County down to San Diego County. You can also find it in Mohave County, Arizona.
It likes to grow on hillsides in places like the Transverse Ranges and the Inner South California Coast Ranges. It's often found near the western edge of California's Central Valley, specifically the San Joaquin Valley.
About Douglas' Tickseed
Coreopsis douglasii is an annual herb. This means it completes its whole life cycle, from seed to flower to seed, within one year. It usually grows one or more straight stems that can reach about 25 centimeters (about 10 inches) tall.
Leaves and Stems
The leaves of this plant are a bit fleshy. Most of them grow around the bottom of the stem. They can be up to 8 centimeters (about 3 inches) long. Their shape is usually long and thin, or they might be divided into several thin sections.
Flowers and Fruit
Each stem has a single flower head at the top. This head has a rounded base made of pointed, leaf-like parts called phyllaries. The center of the flower head is filled with many tiny yellow disc florets. Around the edge, there are 5 to 8 bright yellow ray florets, which look like petals. Each of these ray florets is usually less than a centimeter long. After the flower blooms, it produces a small, dry fruit called an achene.
