About
Croton setiger is a species of plant known in English as turkey mullein, dove weed, and fish locoweed. (Not to be confused with Murdannia nudiflora, which is often called doveweed.) It is native to most of the western United States and northwest Mexico. It has naturalized elsewhere, including parts of Australia and Central Chile. It is sometimes spelled Croton setigerus and was formerly known as Eremocarpus setigerus.
This is a squat plant with furry, feltlike, hexagon shaped leaves, pale pink green in color. The small green flowers are covered in soft bristles.
How to grow it
Croton setigerus is used as an ornamental plant; its low and rounded form fills a pot.
The foliage is toxic to animals, and the crushed plants, called shä'um by the Pomo people and kē-chil' wä-ē-mök' by the Yuki people, were used by both Native Americans and later immigrants as a fish toxin to stupefy fish and make them easy to catch. When crushed, the leaves have a sweet odor that some find unpleasant.
