Lamium is a plant genus comprising a few dozen species of flowering plants that are native to Europe, Asia, and Africa. One species that is particularly popular among gardeners and landscapers is Lamium maculatum. This perennial flowering plant is commonly known as the spotted deadnettle. It grows 6 to 12 inches in height and spreads up to 30 feet. The variegated foliage is medium green and gray. while the flowers are pink. Its mat growing habit leads to the formation of wide, dense mounds of foliage that are perfect for ground cover or edging material.

This species of flowering plant grows comfortably in hardiness zones 3 to 8. It isn’t drought tolerant and generally prefers partial sunlight or shade, rather than direct sunlight.
Soil Conditions

Propagation
There are a few options for propagating the spotted deadnettle. One method involves dividing the roots. It is commonly called crown division. After the plant is divided, each portion is re-planted.
