(Wooly Arabian Sage) "Radiant" is the word that garden writer and Salvia specialist Betsy Clebsch uses to describe the halo of white hairs covering the foliage and calyxes of Salvia lanigera.
Tiny, deep purple flowers contrast dramatically with gray-green, deeply lobed leaves and the plant's overall silvery look. The fuzzy hairs help conserve moisture in low-water environments. The plant's essential oils, which make it pleasantly aromatic, are currently the focus of medical research on antimicrobial and antioxidant properties.
Wooly Arabian Sage is native to desert and coastal areas throughout the Middle East including Arabia, Egypt, Iran, Israel and Turkey. French clergyman Jean-Louis Marie Poiret (1755-1834), a botanist and plant explorer for France's King Louis XVI, described the sage in 1817. However, this is a rare plant in commercial horticulture.
Wooly Arabian Sage is an herbaceous perennial in areas with warm winters. Yet it returns even when grown as an annual, because it reseeds freely. In its native lands, Wooly Arabian Sage can reach up to a foot tall with branches that curve upward like a candelabra. However, it's often more petite elsewhere and works well tucked between other, taller plants.
