Lavandula dentata, commonly known as French lavender, features a striking appearance that is easily recognized by its unique foliage and blossoms. The plant boasts a bushy growth habit, embellished by grey-green leaves that have a distinctive shape, serrated on the edges, which resembles jagged teeth, hence the name "dentata" which means toothed in Latin.

  • water dropWater

    French Lavender should be watered regularly but infrequently, ensuring that the soil has dried out slightly between watering sessions to prevent root rot. In the summer, watering every 7-10 days with about 0.5 gallons per plant should suffice, depending on climate conditions. During the winter, reduce watering to every two to three weeks with the same amount of water, as the plant will enter a semi-dormant state and require less moisture.

  • sunLight

    French Lavender thrives best in full sunlight, requiring at least 6 to 8 hours of direct sunlight daily. Place it in a south-facing location where it will receive abundant light to encourage healthy growth and ample flowering.

  • thermometerTemperature

    French Lavender prefers warmer temperatures and does well in a range from 60 to 70 degrees Fahrenheit, but can tolerate temperatures down to the low-40s without being damaged. Ideally, protect the plant from extreme cold and frost, as temperatures lower than 40 degrees Fahrenheit can be harmful to the plant's health.

  • scissorsPruning

    Prune French Lavender after its first flowering and again in late summer to maintain its shape and encourage a second bloom. Cut back about a third of the growth to promote new growth and air circulation. The best time to prune is typically just after the plant blooms, which can vary depending on your climate.

  • circleLife cycle

    French Lavender (Lavandula dentata) starts its life as a seed, which, once germinated in warm, well-drained soil, emerges as a seedling with delicate, true leaves characteristic of the lavender species. As a young plant, it experiences a vegetative stage of growth, where it develops a woody stem and distinctive foliage, alongside the formation of its signature oil-rich, serrated leaves. Upon maturity, French Lavender enters the flowering stage, typically producing its vibrant purple to violet-blue flowers in the spring or early summer, attracting pollinators to its fragrant blooms. After pollination, the flowers develop into fruit in the form of small nutlets, which contain seeds that can be dispersed for reproduction. Eventually, as a perennial, the plant will go through a period of dormancy in colder months, only to resume growth and flowering in the following season. With proper care and favorable conditions, French Lavender can live and thrive for several years, going through multiple flowering cycles.

      Spring to Summer

    • Lavender (Lavandula dentata), known for its fragrant leaves and decorative flowers, is commonly propagated via stem cuttings. The ideal time for taking cuttings is during the late spring or early summer when new growth is vigorous yet still semi-hard. A cutting should be about 3 to 4 inches (about 7.5 to 10 cm) in length, taken just below a node, the point on the stem where leaves attach. This section is then stripped of the lower leaves, leaving two or three pairs at the top. The base of the cutting is dipped in a rooting hormone to promote root development and planted in a well-draining soil mix. It's important for the soil to stay moist but not waterlogged. The cuttings are typically placed in a warm, shaded place until they root, which usually takes several weeks.
