Habitat : Jacobaea maritima is native to the western and central Mediterranean region, in northwest Africa (Morocco, northern Algeria, Tunisia), southern Europe (Spain, Gibraltar, southern France including Corsica, Italy including Sardinia and Sicily, Malta, Slovenia, Croatia, Hercegovina, Kosovo, Montenegro, Serbia, Macedonia, and Greece), and the far west of Asia (Turkey). It occurs primarily on cliffs and rocky coastal sites, more rarely inland.

It is also naturalised further north in Europe (north to Great Britain and Ireland, where occurring mainly in mild coastal areas) and locally in North America.
Description:
Jacobaea maritima is a perennial plant. It is a very white-wooly, heat and drought tolerant evergreen subshrub growing to 0.5–1 m (1.6–3.3 ft) tall. The stems are stiff and woody at the base, densely branched, and covered in long, matted grey-white to white hairs. The leaves are pinnate or pinnatifid, 5–15 centimetres (2.0–5.9 in) long and 3–7 centimetres (1.2–2.8 in) broad, stiff, with oblong and obtuse segments, and like the stems, covered with long, thinly to thickly matted with grey-white to white hairs; the lower leaves are petiolate and more deeply lobed, the upper leaves sessile and less lobed. ....CLICK & SEE >…..(01): ..…...(1) :http://www.maltawildplants.com/ASTR/Jacobaea_maritima_subsp_sicula.php

The tomentum is thickest on the underside of the leaves, and can become worn off on the upper side, leaving the top surface glabrous with age. The flowers are yellow, daisy-like in dense capitula 12–15 millimetres (0.47–0.59 in) diameter, with central disc florets surrounded by a ring of 10–13 ray florets, and enclosed in a common whorl of bracts at the base of the capitulum. The seeds are cylindrical achenes. It belongs to the groundsel or ragwort family, of which there are nearly 900 different species known to botanists.

Cultivation & propagation: Jacobaea maritima is widely used in horticulture for its silvery foliage. It is winter-hardy in USDA Zones 8-10, 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. Many cultivars have been selected for particularly dense silvery tomentum, such as ‘Cirrus’, ‘New Look’, ‘Ramparts’, ‘Silverdust’, ‘Silver Filigree’, and ‘White Diamond’. It has been recommended in North America for its fire resistance resistance to browsing by deer, and its salt tolerance.

This plant is perennial, propagated by cuttings, layers, or seeds.
Medicinal Uses: The fresh juice is said to remove cataract. A few drops of the fresh juice are dropped into the eye. To learn more click & read
