Herbs - Rosemary : Introduction

Rosemary (Rosmarinus officinalis) 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 2 m. The leaves are evergreen, 2-4 cm long and 2-5 mm broad, green above, and white below with dense short woolly hairs. The flowers are variable in colour, being white, pink, purple, or blue.

The name rosemary has nothing to do with the rose or the name Mary, but derives from the Latin name rosmarinus, which is presumed to mean "dew of the sea", though some think this too may be derived from an earlier name.

Rosemary is often commonly associated with memory and/or remembrance of the past.

Cultivation and uses

The fresh and dried leaves are used frequently in traditional Mediterranean cuisine as a herb; a tisane can also be made from them. They are extensively used in cooking, and when burned gives off a distinct mustard smell.

Since it is attractive and tolerates some degree of drought, it is also used in landscaping, especially in areas having a Mediterranean climate. It can in fact die in over-watered soil, but is otherwise quite easy to grow for beginner gardeners. It is very pest-resistant.


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 too 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 10-15 cm long, stripping a few leaves from the bottom, and planting it directly into soil.
