Lavender is a sun-loving plant, so it's not surprising that it does best in full sun. However, lavender will also do well in partial shade, as long as it receives at least six hours of sunlight each day. In very hot climates, some afternoon shade may be beneficial to prevent the leaves from burning. Lavender can also tolerate light shade, but it may not bloom as profusely in these conditions. If you live in an area with hot summers and cool winters, lavender may do best in a spot that gets morning sun and afternoon shade.
