An evergreen perennial, winter savory is a low-growing, semi-woody herb in the mint family, Lamiaceae, and is also commonly known as creeping, mountain, or Spanish savory.Native to the temperate climates of the Mediterranean basin, it forms low growing and multi-branched mounds that grow 8 to 15 inches high, with a 12- to 24-inch spread.The glossy, 1-inch leaves are dense, slender, slightly leathery, and highly aromatic, appearing opposite on the stems. Small, dainty flowers appear on terminal spikes throughout summer in colors of mauve, pink, and white.Cold hardy in USDA Hardiness Zones 6-9, these plants go dormant in winter and can lose many of their mature leaves along the stem tips. But new growth quickly appears on the bare stems once longer days and warmer temperatures return.
