“Lavandin is a hybrid plant, developed by crossing the true lavender plant (Lavandula Officinalis) with the aspic or “spike” lavender (Lavandula Latifolia). The resulting plant is called Lavandula Hybrida, and it exists in a great number of forms (varieties), a few of which are distinctly more interesting than the others. When visiting the lavender fields, aspic fields and the cultivated lavandin areas, one is often told that the blue color of the lavender and the grayish color of the aspic will show up in a nuance in the lavandin, revealing which one of the parent plants is predominant in the hybrid”
Lavandin Absolute (aromatherapy)
Lavandin absolute from concrète is a viscous, very dark green liquid of pronounced herbaceous odor, resembling that of the flowering herb closely. In comparison to the Lavandin Oil, the absolute from concrète has a deeper sweetness and body as well as a rich undertone. The camphoraceous-camphene-like topnotes of the oil are subdued, if present at all, in the Absolute.
