Rosemary is one of those wonderful herbs that makes a beautiful ornamental plant as well as a versatile culinary seasoning. Its Latin name, Rosmarinus officinalis, means "dew of the sea," and rosemary is most closely associated with the cooking of the Mediterranean region.
In warm climates, rosemary can be planted at any time. In climates with cold winters, plant it in the spring after the soil warms up, at least a week or so after the last frost date. When grown as a perennial in warm climates, newly planted seedlings will reach mature size and begin flowering in their second season.
