“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”
