About Reddened Clarkia (Clarkia rubicunda) Clarkia rubicunda is a flowering plant endemic to California. It is found mostly in the central part of the state. The plant is known by the common names ruby chalice clarkia and farewell to spring. It is similar in appearance to another flower of genus Clarkia also called farewell to spring. It bears attractive poppy-like blooms with wide, cup-shaped corollas of four pink or purplish petals. The corolla of the flower sometimes has a bright red center. As the common name suggests, it blooms in June and July.
