Lavandula stoechas, commonly known as French lavender or Spanish lavender, is a subshrub in the family Lamiaceae. Native to the Mediterranean region, it is known for its distinctive, fragrant flowers and aromatic foliage. This plant prefers subtropical climates and is often used in gardens and landscapes for its ornamental value and pleasant scent.
French lavender thrives in bright, direct sunlight and prefers moderate temperatures. It should be watered sparingly, allowing the soil to dry out almost completely between waterings. This plant enjoys low to moderate humidity and should be protected from extreme cold.
Soil
Lavandula stoechas prefers well-draining soil, ideally a loamy mix. It can tolerate poor soil conditions but thrives best in soil with moderate nutrient concentration. Good drainage is essential to prevent root rot.
Fertilizer
A balanced fertilizer with a nutrient composition of 5-10-5 can be applied during the growing season. Fertilize sparingly, as over-fertilization can lead to excessive foliage growth at the expense of flowers.
Repotting
Repotting should be done in the spring when the plant outgrows its container. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Gently remove the plant from its old pot, loosen the roots, and place it in the new pot with fresh soil.
Propagation
Lavandula stoechas can be propagated through cuttings. Take softwood cuttings in late spring or early summer, dip the cut end in rooting hormone, and plant it in a well-draining soil mix. Keep the cuttings in a warm, bright location until they root.
Pruning
Pruning is essential to maintain the shape and health of the plant. Prune after the flowering season by cutting back the spent flower stems and shaping the plant. Avoid cutting into the woody part of the plant, as it may not regrow.
Toxicity
Lavandula stoechas is generally non-toxic to pets and humans. However, ingestion of large quantities may cause mild gastrointestinal upset. The essential oils can be irritating to the skin for some individuals.
Additional
To encourage bushier growth and more prolific flowering, pinch back the tips of young plants. Mulching around the base of the plant can help retain moisture and suppress weeds. Regularly check for pests such as aphids and spider mites, and treat as necessary.
