How to identify Salvia officinalis

Salvia officinalis shrub (Common sage, Garden sage, Dalmatian sage, Broadleaf sage)


Bushy, aromatic, evergreen subshrub, forming a spreading cushion shape densely covered with its broad grey-green leaves that become almost white in the summer.

It is very branched from the base with white hairy stems bearing numerous hairy, grey-green leaves of various sizes.

Long stalks with terminal or axillary racemes of violet-blue flowers rise above the foliage.

The shrub has an average height of 30 to 60 cm  (1 to 2 ft)  and a width of 60 to 90 cm  (2 to 3 ft).

This species varies widely in terms of its inflorescence, leaf size and shape, calyx size and hairiness. 

Botanists define it as a shrub because of its woody stems; however, it looks very much like an evergreen herbaceous perennial.

Salvia officinalis stem (Common sage, Garden sage, Dalmatian sage, Broadleaf sage)


The stems are upright, very branched from the base and covered with short, dense white hairs. They are initially herbaceous but become woody over time.

They are squared, with opposite leaves at each node, each pair at right angles to the next. The leaves are bigger at the base of the stem and become smaller at the top of the stem.

The flower stems are longer than the foliage stems and have terminal or axillary racemes of flowers (simple or with 2 opposite branches at the base of the terminal inflorescence).

Salvia officinalis leaf (Common sage, Garden sage, Dalmatian sage, Broadleaf sage)


The leaf is densely-haired, grey-green and rugose on top, and whitish underneath because of its dense short hairs. It has a clear netted venation that can be easily seen on the underside.

The shape of the leaf is ovate-oblong to elliptic. It is entire, with a crenulate margin (a margin with small rounded teeth) and petiolate (has a stalk).

The size varies between 1.8 to 7.7 cm ( 0.7 and 3.1 in) long and 0.8 to 3 cm  (0.3 and 1.2 in) wide.

The aroma of the leaves is pungent and can be noticed even without crushing them. 

There are numerous cultivars with showy variegated leaves, beautiful inflorescences and with different aromas. 

Salvia officinalis flower (Common sage, Garden sage, Dalmatian sage, Broadleaf sage)


The inflorescence is a raceme which varies in height from 10 to 40 cm (3.9 to 15.7 in), with several whorls composed of 4 to 12 violet-blue flowers. The base of the inflorescence has two opposite green, ovate, acute bracts that remain after the flower falls off.

The corolla is two-lipped, the upper lip has 2 lobes laterally compressed, forming a hood, and the lower lip has 3 lobes, with the middle lobe larger. The stamens are inserted under the hood of the corolla with the anthers peeking outside, and the pistil sticks out from the top.

Each flower is held inside a green or maroon-coloured calyx that is bell-shaped and 2-lipped with five triangular teeth, three on the upper lip and 2 on the lower one.

The flowers bloom in early summer.

    Salvia officinalis Usage


    The Common Sage is a very attractive shrub with its dense grey-green, broad and woolly foliage and long violet-blue inflorescences rising above the foliage.

    It can be used as a solitary plant or planted in a group. Can be planted in pots, beds or borders. In rock or gravel gardens.

    Due to its aroma, it is a plant of choice for aromatic gardens.

    It is ideal for planting on the borders of paths to perfume the air as they are brushed when passing by.

    This sage usually becomes too woody after 4 to 5 years and needs to be replaced.


    Salvia officinalis has been used in traditional medicine since ancient times. It was used for numerous health issues such as seizures, ulcers,  gout, rheumatism, inflammation, dizziness, tremor, paralysis, diarrhoea, and hyperglycemia. No wonder it was stored in the offcina (the medicine storeroom of monasteries), leading to its name officinalis.

    Studies have demonstrated some medicinal properties such as anticancer, anti-inflammatory, antinociceptive, antioxidant, antimicrobial, antimutagenic, antidementia, hypoglycemic, and hypolipidemic.


    Due to its savoury, slightly peppery flavour, Common sage leaves have been used, fresh or dried, in the preparation of many foods since ancient times and Sage tea was prepared to treat several illnesses.

    It is commonly used in roasted or stewed dishes of beef, poultry, pork and lamb.

    It is also used to flavour cheese, vinegar, olive oil, and alcoholic drinks.


    Due to its intense aroma and antiseptic properties, the essential oil of Salvia officinalis is used in the production of perfumes and cosmetics such as soaps, shampoo and toothpaste.


    The flowers of this sage are a good source of nectar, being very attractive to bees, butterflies, other beneficial insects, and sometimes even hummingbirds. They enhance the biodiversity of your garden.

    Insect repellent

    Sage can act as an insect repellent due to its strong odour. It is said to repel mosquitos, cabbage moths and carrot flies. So it is a good plant to have, especially near your vegetable garden.


    In ancient times the Romans considered this sage a “holy herb” and used it in their religious rituals.

    Salvia officinalis Habitat

    This shrub grows in the typical Mediterranean landscape at altitudes up to 2900 m (9500 ft).

    It is seen in dry shrublands, rocky slopes, and grasslands in free-draining soil.

    It grows in coastal areas and across hillsides and mountains.

    How to care for Salvia officinalis

    Cold exposure

    This shrub is hardy, tolerating temperatures down to -15ºC (5ºF) or colder, as long as the soil is well drained. It does not support cold and humid soil. It is moderately frost hardy if the temperatures are not too low.

    However, until it is fully established, it will need winter protection.  Add some mulch to protect the roots from low temperatures and the foliage from the wet soil.

    Sun exposure

    Needs full sun (at least 6 hours per day) to maintain its best colour and compact shape.

    It can tolerate some shade, but it is likely to become more floppy as the stems stretch to the light. It also won´t get as many flowers nor produce as much essential oil.


    It likes hot, well-drained to dry, stony or sandy soils. It especially dislikes wet soil, which makes it more exposed to fungal diseases.

    If prefers poor soils, if they’re too fertile, the shrub tends to become leggy and has more difficulty tolerating drought and cold temperatures.

    It thrives best in mildly acid and neutral soils. But it can also grow in mildly alkaline soil.


    Once established, this Sage is drought tolerant and can go for some time without water (about 4 months if the temperature is not too hot). 

    Overwatering will probably kill it. In particular, the combination of heat and humidity can lead to fungal disease.

    During the first two years after planting, you will need to water the young plant every two to three weeks during the summer.  Allow the soil to dry out between watering. In case of a heat wave, water more frequently. Monitor your plants closely and look out for any signs of stress.

    To preserve the soil´s moisture, you should add mulch around the root area of the plant (but not too close to the base). Wood chips and gravel are good options for mulching. 

    Other conditions

    Salvia officinalis will become leggy and lose its nice compact shape over the years. So, you should propagate it and replant a new sage every 4 or 5 years.

    The best season to plant is during Autumn, so it will have all winter to develop its roots. In very cold areas it is best to plant during the spring as long as there is available water throughout the summer to survive while developing its roots.

    How to prune Salvia officinalis

    Pruning is essential to maintain the plant´s compact decorative shape and flowering. It should be done twice a year.

    • A hard prune in early spring in order to maintain its shape and compactness. Take care to always prune above the new shoots that are appearing at the base.
    • A light prune after flowering (usually in summer) to encourage bushiness and possibly another flush of flowering after a few weeks. This prune should be done just below the inflorescence to the next pair of new buds.

    If you want to use your sage as a herb for the kitchen, then the best time to harvest is just before flowering because this is when its oil content is highest. Cut off the top 20cm (8 on) of tender growth.

    How to propagate Salvia officinalis

    Sage can be propagated in different ways:

    • Propagate by seed sown in late winter and early spring.
    • Propagate by softwood cuttings taken in early spring, by semi-hardwood cuttings taken in later spring and summer, or by hardwood cuttings taken in autumn
    • Propagate by layering in spring or autumn

    A good online source for plant propagation techniques can be found at RHS.
