Rosemary is pine-scented herb, that grows into a small shrub that can reach up to four feet in height in an ideal climate. The plant produces flat, needle-like leaves that are about one-inch in length, green in colour with a silver-grey sheen on the underside. Rosemary?s needle-like leaves grow in thick rows, straight upward on multi-branched, woody stems. The fragrance is very pungent, with a bitter and astringent, pine-like taste. When mature, white or blue, two-lipped flowers bloom at the tops of the stems. Rosemary is generally harvested prior to flowering.
