Lavandula
"Lavender"

Lavender is a sweet scented herb that grows widely around the Mediterranean. It is native to tropical Africa and SE India as well. Its cultivation is as ancient as civilization itself. The Romans associated it with bathing (Lavare - to wash) providing the origin of its basic name. Lavender's two - lipped asymmetrical spikes of fragrant violet flowers open in succession from a calyx or cup. Every part of the plant is fragrant, but it is the calyx, not the flowers that provide the best scent and are best for sachets. There are approximately 28 species of lavender and over 200 varieties. The leaves age to a pale grey, and are linear and hairy, strategic assets for survival in hot dry places. The fragrant scent actually makes it unappetizing to insects and foragers.

In the sunny fields of Provence, France, hundreds of acres of Lavender (L. x intermedia) bloom. This hybrid lavender, crossed naturally by nature, was discovered in 1930 by French farmers and found to be far superior in scent to those of L. augustifolia or L. latifolia, its parents. The hybrid is called “Big Lavender” or “Lavandin” for the strength of fragrance in its oil, an essential ingredient for the perfume factories at Grasse, and the 2000 employees they hire.

The Fragrance Garden, newly renovated this spring, is filled with many fragrant plants and herbs including Lavandula, Spanish lavender in particular. This garden is especially designed for those with impaired vision, who can touch and smell the many ornamental and medicinal plants that grow there.
