The site was located at approximately According to recommendations, individual plants were spaced 1 m apart, watered every 15 days for 8 to 12 h drip irrigation and no fertilised agent was used. The ionisation mode was electronic impact at 70eV in positive mode and the signal acquisition was the scan mode from 40 to The chromatographs can be found in supplementary information chromatograph 1a to 1e.
Identification of essential oil components - Essential oil components were identified by comparison of their mass spectral fragmentation pattern with NIST mass spectral library database  and based on their Van Den Dool retention indices determined with reference to a homologous series of normal alkanes, C7-C40, and compared with the ones reported in literature [31, 32]. As expected, there are still some compounds that could not be identified because of their low signal-to-noise ratios or limitation of the mass spectral database.
Relative area of each essential oil component was carried out by a peak area normalization measurement total ion current [31, 32]. After inoculums absorption by agar, sterile discs of Whatman No. A control was used for each case by not exposing the bacteria to any distilled product. Discs were deposited at equal distance on the surface of the agar. The Petri dishes were left at room temperature for 5 min before incubation to ensure a good diffusion of the distilled product in the agar.

source While the plant grows in parts of Eastern Europe, Hungary, and Spain, cultivation is mainly in France. The bright purple-blue flowers commonly found in true lavender are often a grayer hue in the spike variety.
The essential oil is very penetrating, more herbal than floral, and retains a higher concentration of camphor than true lavender.
