A low-growing garden plant, lesser calamint is a tough, drought tolerant plant that blooms most of the summer with a cloud of white to lavendar flowers over mats of gray-green foliage. These plants make great fillers. They also attract a large number of bees, butterflies, and other pollinators. Calamints are cousins to the herbal mints and are very fragrant but do not spread as aggressively.

Disease, pest, and problem resistance
The strong scent when crushed makes it resistant to deer and rabbits.
Native geographic location and habitat
Southern Europe and Great Britain

The multitudes of flowers are very attractive to bees to the extent that they should not be planted near walkways if bees are a problem. Butterflies and hummingbirds also appreciate the flowers.
The egg-shaped leaves are small, gray-green and form mats about one foot high.
Delicate pale lavender to white tubular flowers bloom all over the plant.
Small rounded pods containing multiple light brown seeds. Lesser calamint is easily grown from seed.
