About Sibara filifolia (Greene) Greene
Sibara filifolia is an annual herb that produces a hairless stem, which is sometimes waxy, and reaches a maximum height of around 30 centimeters. Its leaves are very narrow, almost strandlike, measuring less than 1 millimeter wide and growing to about 1.5 centimeters long. Each of its flowers has four spoon-shaped lavender petals that are a few millimeters long. Its fruit is a flattened, elongated silique up to 4 centimeters long, which holds tiny seeds. Sibara filifolia grows in coastal sage scrub on two islands off the coast of southern California.
