Safety Overview
1.Lamium — Introduction & Highlights
Lamium maculatum, commonly known as Spotted Dead-nettle or Spotted Henbit, is a charming perennial herbaceous species belonging to the Lamiaceae family, which also includes true mints. Native to Europe, temperate western Asia, and North Africa, it has become widely naturalized globally. This plant is characterized by its prostrate, spreading growth habit, typically reaching 6-9 inches in height, forming a dense mat as its square, hollow stems root at the nodes. The foliage is a key ornamental feature, displaying opposite, toothed, pointed oval to heart-shaped leaves, often over 3 inches long.
A distinctive silvery stripe or blotch frequently adorns the midvein, giving rise to numerous variegated cultivars. Unlike its stinging nettle namesake (Urtica dioica), Lamium maculatum leaves are non-urticating, hence the 'dead-nettle' moniker. From late spring through early summer, and sporadically into fall, the plant produces small, hooded, two-lipped flowers in whorls (verticillasters) along the upper stems. These flowers, typically pink to purple, but sometimes white, are highly attractive to pollinators, especially bumblebees.
After flowering, inconspicuous dry fruits, each containing four nutlets, develop. Lamium maculatum thrives in partial to full shade, preferring moist, humus-rich, well-drained soils, making it an excellent groundcover for challenging shady areas and an adaptable addition to various garden designs.
