La Calamintha sylvatica, also known as calaminta, calamento, catnip or catmint depending on the region, is a perennial herbaceous plant belonging to the Lamiaceae family. It stands out both for its aromatic and medicinal properties as for your ornamental value in gardens and natural spaces. Its aroma is reminiscent of a mixture of peppermint and lavender, making it a favorite for those looking to enrich their orchard or garden with functional and, at the same time, decorative species.
Calamintha sylvatica is situated within the group of perennial plants and is characterized by a great resistance and a remarkable ability to adapt to different soils and environmental conditions. Traditionally highly valued in folk medicine and gastronomy, calaminta is also highly valued for its resilience and low maintenance, making it suitable for both experienced and amateur gardeners.
Botanical characteristics and morphology
La Calamintha sylvatica It is a suffruticosa plant at the base, with a tendency to develop quadrangular stems, slightly pubescent and with a erect that can reach between 40 and 60 cm highThis species forms dense clumps thanks to its short, creeping rhizomes.
- Sheets: Opposite, oval, with toothed margins in the subspecies sylvatica (an important distinction from other calamintas), velvety texture, shiny dark green, and petiolate.
- Flowers: Small, tubular, white or with violet hues, they are grouped in terminal inflorescences in clusters. Each flower typically measures between 15 and 20 mm in length and has a bilabiate calyx, very characteristic of the Lamiaceae, and a bilabiate corolla.
- Fruit: Tetra-nutula, typical of the family.
- Aroma: The whole plant gives off an intense menthol aroma, consequence of the presence of essential oils such as piperitone, limonene, menthol, pulegone and sabinene, components responsible for its aromatic and medicinal applications.
Within the species, we can find subspecies , the nepeta (leaf margins slightly toothed) and sylvatica (more pronounced margins and more vigorous growth). In some regions, subspecies are frequently used interchangeably for the same traditional purposes, which highlights the importance of understanding their botanical characteristics.
Distribution, habitat and ecology
Calaminta sylvatica is native to Western Europe, but currently has a wide distribution in Europe, especially in the mediterranean basin and the continental center. It is easily found in the Iberian Peninsula, northern Italy and France, even reaching areas of southern Germany and the Balkans.
- Typical habitats: clearings and forest margins, roadsides, stony slopes, embankments, poor soils, walls and scrubland.
- Altitude: It can be found from sea level to altitudes close to 1400 meters.
- Substrate type: Adapts to both calcareous and siliceous soils, always preferring well-drained environments and avoiding waterlogging. It tolerates somewhat nutrient-poor soils, but appreciates a minimum organic matter content.
- Climate: It prefers temperate climates, tolerates cold and even light frosts. It withstands sunny exposures and drought conditions, making it ideal for xeriscape and low water consumption gardens.
Calamintha sylvatica care
Calamintha sylvatica is a plant of easy to grow and low maintenance, making it perfect for both beginners and advanced gardening enthusiasts.
Light and exposure
- Tolerant to both direct sun as the semi-shadowIdeally, a bright location is ideal, but in particularly warm regions, it can be protected from the intense sun during the middle of the day to prevent the foliage from drying out excessively.

Irrigation
- Requires moderate wateringThe substrate should dry out between waterings. Excess moisture is its main enemy, which can cause root rot and the growth of fungus.
- In a pot, ensure that the substrate does not remain wet for long periods.
- In the garden, it can survive periods of drought once well established.
Fertilization
- It is not particularly demanding in fertilizers. It is recommended to apply balanced fertilizer In spring and summer, every 4-6 weeks to enhance plant vigor and flowering.

Pruning and maintenance
- An light pruning After flowering, it helps maintain the compact shape of the plant and stimulates the regrowth of young stems.
- You can make a more drastic pruning at the end of winter to rejuvenate old or untidy plants, which will promote dense and vigorous sprouting in the following season.
Multiplication and propagation

- By division of bushes: It is recommended to fertilize every 2-3 years to rejuvenate the plant and maintain its vigor. The best time is early spring or early fall, when the plant is not in full bloom.
- By cuttings: It can be propagated by taking stem cuttings, preferably in early spring or late summer. Place the cuttings in a light substrate and keep slightly moist until they develop roots.
