|Rosemary in flower|
| Rosmarinus officinalis|
Rosemary is a woody, perennial herb with fragrant, evergreen, needle-like leaves. It is native to the Mediterranean region. It is a member of the mint family Lamiaceae, which also includes many other herbs.
Forms range from upright to trailing; the upright forms can reach 1.5 m tall, rarely 2m.
The leaves are evergreen, 2-4 cm long and 2–5 mm broad, green above, and white below with dense short woolly hair.
Flowering, very common in a mature and healthy specimens, occurs in summer in the north, but the plants can be everblooming in warm-winter climates; flower colors are variable, being white, pink, purple, or blue.
Coming from the Latin words ros marinus, rosemary translates into dew of the sea. It was said to be draped around Aphrodite when she rose from the sea and was originally born of Ouranos's semen. Today, the goddess Aphrodite is associated with rosemary, as is the Virgin Mary, who was supposed to have spread her cloak over a white-blossomed rosemary bush when she was resting; according to legend, the flowers turned blue, the color most associated with Mary.
Since it is attractive and tolerates some degree of drought, it is also used in landscaping, especially in areas having a Mediterranean climate. It is considered easy to grow for beginner gardeners, and is pest-resistant.
Rosemary grows on friable loam soil with good drainage in an open sunny position, it will not withstand water logging and some varieties may be susceptible to frost. It grows best in neutral to alkaline conditions pH (pH 7–7.8) with average fertility.
Rosemary is easily pruned into shapes and has been used for topiary. When grown in pots, it is best kept trimmed to stop it getting straggly and unsightly, though when grown in a garden, rosemary can grow quite large and still be attractive. It can be propagated from an existing plant by clipping a shoot Template:Convert long, stripping a few leaves from the bottom, and planting it directly into soil.
