Black Mustard
This annual herb is found on almost every disturbed hillside and vacant lot in Orange County. It is easily identifiable by its many small bright yellow flowers. When it has taken over a large area it provides a beautiful carpet of yellow. It only real danger is that completely dries out in late summer and becomes a significant fire danger.
