Broad-leaved lavender

Broad-leaved lavender (Lavandula latifolia Medik.) is a perennial evergreen subshrub belonging to the Lamiaceae family. Characterized by broader, grey-green foliage and a distinct, camphor-like scent, this species is highly valued for the production of essential oils. It is a distinct botanical entity, often contrasted with narrow-leaved lavender (Lavandula angustifolia) due to its different oil composition.

The plant is native to the western Mediterranean region, thriving in rocky, mountainous areas and dry hillsides. It has been cultivated for centuries across Southern Europe, where the hot, dry summers provide ideal conditions for its growth. Unlike other varieties, it prefers warmer temperatures and is highly sensitive to frost during the winter months.

Botanically, the plant develops a woody base with multiple stems reaching up to 60–80 cm in height. The inflorescences are dense, spike-like structures emerging from the tips of the shoots. Its foliage is wider than that of other lavender species, which allows it to adapt to slightly more humid environments than its counterparts, although it still demands excellent drainage.

Cultivation requires full sun exposure and well-draining, slightly alkaline soil. Proper site selection is critical; the crop performs best on slopes or in soil enriched with gravel or sand to prevent root rot. Agronomic practices must include regular pruning in the autumn or spring to prevent the wood from becoming too bare and to encourage fresh growth for the following season.

The primary economic use is the extraction of essential oil used in industrial fragrances, cleaning products, and traditional medicine. Beyond oil production, it serves as an excellent ornamental plant in xeric landscaping, requiring very little water once established. Common pests include spittlebugs and aphids, while root rot remains the most significant disease risk, primarily caused by poor soil drainage.
