Lavender is quite hardy, my little starter plant from last year survived our cold winds, low temperatures, 40 inches of snow, and total neglect in a 6 inch pot on the back patio. I potted it up to a 12 inch pot today.
Although Lavender makes a good companion plant for cabbage, insect wise, cabbages need more water than lavender. Potted up, I can shift the lavender around the garden as needed, and keep it happily on the dry side.
In July/August I will take a cutting or two.
There is something ethereal about a field of blooming Lavender. Appearance, sure, but the scent is unbelievable. Just a guess, the prosaic explanation is one of its medicinal qualities. Lavender is an important relaxing herb that soothes the nervous system.
Lavender essential oil is mostly used externally, and although gentle on skin, is a strong antiseptic against many bacteria, including typhoid, diptheria, streptococcus, and pneumococcus.
The essential oil on burns, bites, and cuts can help them heal without permanent scar tissue.
Lavender is strongly aromatic so a little goes a long way. I have used the flowers in tea, and salads. I enjoy putting flowers in white wine vinegar to keep the flavor past it’s blooming season for salads. I like steeping it in light oil for use in stir fry. Bury blooms in sugar for a delicious flavor.
One day I may have a small field of Lavender, but until then I will have this dream on a star in its 12 inch pot floating around my garden.
