It’s no secret to anyone who knows me well that I love lavender, Lavandula angustifolia. I love its scent, I love how I feel when I smell it and I love the plant itself. It makes a lovely edge for flower beds and pairs magnificently with roses. Many gardeners say that lavender strong fragrance keeps aphids at bay. I find this to be true in my garden. Aphids tend to stay away from the roses that neighbor lavender. Our previous house was attractive to moths, so I used to keep a sachet of dried lavender flowers in my wardrobe to deter them. Not only I no longer saw moths, the sachet kept my clothes smelling fresh.
The name, lavender, stems from the Latin lavare which means to wash since this plant was often used in wash and bath water. The flowers have therapeutic properties and are also used in gastronomy.

Lavender can be cultivated in cooler climates but might need winter protection. Since it is endemic to the Mediterranean, it thrives in full sun and for that reason it won’t bloom in cold climates as prolifically as in warm climates.

Companion plants: Roses benefit from lavender’s fragrant flowers as the essential oils in lavender help to repel aphids. Avoid planting lavender near wormwood.
For medicinal purposes, harvest lavender flowers when they are beginning to bloom but before all the flowers have fully opened. Cut the flowering stalks a couple of fingers above the leaves. It’s easier to harvest the flowers with the stems and garble off the flowers when dried than to pick the fresh flowers off the stems.
Place the flowering stalks on a flat surface in a dry and well ventilated room and dry them at 38 to 40 degrees Celsius (100-104 F). Keep it out of direct light to help maintain medicinal value and vibrant color. Lavender is fully dried when the stems are no longer pliable and snap easily. At this stage, the flowers rub off the stems easily.
