Color: Pink or purplish
Bloom Time: April through November
Lamium maculatum is a prostrate spreading herbaceous perennial up to 2.6 feet (80 cm) tall. It has erect, hollow, and pubescent stems, branched at the base only. The soft hairy leaf blades are up to 8 inches (20 cm) long. They are spotted (hence the Latin name "maculatum"), toothed with long petioles, up to 1.6 inches (4 cm) long. Their shape varies from ovate-triangular to heart-shaped. The inflorescence bears about 2 to 8 hermaphrodite flowers up to 1.2 inches (3 cm) long. They are formed in the leaf axils of the upper leaf pairs. The upper lips of the flowers are helmet-shaped, usually pink or purplish, while the bilobate lower ones are whitish with purple dots. The stamens are located in the upper lip and have orange pollen. The flowering period extends from April through November.
How to Grow and Care
Lamium is undemanding and easy to grow in partial to fully shaded locations. It prefers well-drained soil but will do fine in the dry shade if you provide it with regular watering. A member of the mint family, Lamium spreads quickly, is self-seeding, and will rapidly create a groundcover wherever it is planted. Its brittle, fragile stems help keep it from becoming aggressively invasive and also allow bulbs and other perennials to penetrate its foliage. In regions with cold winters, Lamium is deciduous. In milder climates, it is semi-evergreen. In either case, cut back shabby foliage after the first frost to make way for new growth in the spring. In midsummer, after the blooming period is over, prune plants back by one-third to help prevent them from becoming too invasive. The midsummer shearing also encourages a second flowering period in September. Not picky, spotted Dead Nettles do just fine in average, well-drained soil. There is no need to apply fertilizer, as this can encourage them to become too robust and invasive. See more at How to Grow and Care for Lamium.
