Lavenders are small evergreen shrubs with grey-green hoary linear leaves. The purple flowers are sparsely arranged on spikes at the tips of long bare stalks and produce small nutlet fruits. The fragrance of the plant is caused by shining oil glands imbedded among tiny star-shaped trichomes (plant hairs) that cover the flowers, leaves, and stems. The plants in cultivation do not usually produce seeds, and propagation is accomplished by cuttings or by dividing the roots. The herb is highly regarded for skin and beauty and is commonly used in fragrances and shampoos to help purify the skin. It can be purchased over-the-counter (OTC) from drugstores, and some versions are used to add flavour to baked goods and foods.
