Definition: Lavandula latifolia, commonly known as spike lavender, is a flowering plant species within the genus Lavandula, belonging to the family Lamiaceae.
Overview: Lavandula latifolia is native to the western Mediterranean region, particularly found in southern Europe, including Spain, Portugal, and parts of southern France. It typically grows in dry, rocky, or scrubland habitats at low to mid elevations. The plant is widely cultivated for its essential oil, which is used in aromatherapy, perfumery, and certain medicinal applications due to its distinct chemical composition.
Etymology/Origin: The genus name "Lavandula" is derived from the Latin word "lavare," meaning "to wash," reflecting the historical use of lavender in bathing and cleansing. The species epithet "latifolia" comes from the Latin words "latus" (broad) and "folium" (leaf), referring to the plant's relatively broad leaves compared to other lavender species.
Characteristics: Lavandula latifolia is a perennial shrub that typically reaches heights of 30 to 60 centimeters. It features narrow, lanceolate to oblong leaves that are grey-green in color and covered with fine hairs, giving them a slightly fuzzy texture. The flowering stems bear dense, terminal spikes of pale violet to lilac flowers that bloom from late spring to mid-summer. The plant exhibits a strong, camphoraceous aroma, more pungent than that of Lavandula angustifolia (common lavender), due to higher levels of cineole in its essential oil.
The essential oil of Lavandula latifolia is chemically distinct, with a high concentration of 1,8-cineole (eucalyptol) and camphor, making it less suitable for certain cosmetic applications but valuable in respiratory therapeutics and as a fragrant additive in industrial products.

The species is sometimes hybridized with Lavandula angustifolia to produce Lavandula × intermedia, commonly known as lavandin, which is widely cultivated for commercial essential oil production.
