Silver Ragwort (Jacobaea maritime) is a perennial plant species in the genus Jacobaea in the family Asteraceae, native to the Mediterranean region. It is widely cultivated as an ornamental plant for its white, felt-like tomentose leaves. Silver Ragwort is a very white-wooly, heat and drought tolerant evergreen shrub growing to 0.5–1 m tall. The leaves are pinnate, 5–15 cm long and 3–7 cm broad, covered with long grey-white hairs. The flowers are yellow, daisy-like in dense capitula 12–15 mm diameter, the seeds are cylindrical achenes. Jacobaea maritima is native to the western and central Mediterranean region, it occurs primarily on cliffs and rocky coastal sites, more rarely inland. As with many other densely tomentose plants, the tomentum on the leaves is used by some species of bees. Jacobaea maritima is widely used in horticulture for its silvery foliage. It is winter hardy, tolerating winter temperatures down to -12° to -15 °C, tolerant of light shade but preferring full sun. In colder areas it is grown as an annual plant.
