Dead Nettle is a perennial herb that can spread and reach heights of nearly 2 feet. It typically flowers from late spring to early summer and is often utilized as ground cover in shaded or woodland areas. This plant thrives in dry shade where other vegetation struggles to survive. Its stems can root upon contact with the soil, which can lead to aggressive growth and potential invasiveness if not managed properly. Dead Nettle is drought-tolerant, prefers full to partial shade, and does not fare well in direct sunlight. To prevent it from becoming leggy, pruning it back to about 6 inches is advisable. Propagation can be achieved through division in the spring or by taking terminal cuttings during the same season. When planting, it is recommended to space the plants 12 to 18 inches apart. While generally resistant to diseases, it may attract snails and slugs. The cultivar L. galeobdolon 'Variegatum' features leaves that are silver-variegated, except for the edges.
