Lamium maculatum 'Cosmopolitan'

Spotted deadnettle (Lamium maculatum 'Cosmopolitan') is an herbaceous perennial with striking mid-green foliage liberally splashed with silver and purple. Its moderately fragrant, white or pink flowers bloom in the spring producing spindle seeds. It is an ideal companion for other shade-loving plants, and does well in containers or rock gardens as long as it's not too wet. This fast-growing perennial is drought and heat tolerant, and quickly forms a dense mat of foliage perfect for ground cover. It also produces attractive berries that will attract birds to the garden. Spotted deadnettle is a versatile perennial with great ornamental value.

watering

Water spotted deadnettle (Lamium maculatum 'Cosmopolitan') when the top inch of soil feels dry to the touch. Do not allow the soil to dry out completely. You can water your plant with 1 or 2 deep soakings per week, usually every 2-4 days. Water in the morning so leaves have time to dry throughout the day and to avoid introducing fungal diseases due to the foliage staying wet overnight. Avoid waterlogging or soggy soil that can cause root rot.

sunlight

Spotted deadnettle (Lamium maculatum 'Cosmopolitan') grows best in full sun to partial shade, meaning it should receive 4-8 hours of sunlight each day. During periods of extreme heat, some additional shade might be beneficial for the plant. When grown in partial shade, the foliage of the plant will appear darker in color due to fewer hours of direct exposure to sunlight. In either full sun or partial shade, the Spotted deadnettle grows best when the temperature ranges between 60-80 degrees Fahrenheit. It should be placed in an area that receives bright indirect light for most of the day.

pruning

Spotted deadnettle should be lightly pruned in the spring before new growth begins. This will help maintain the plant's desired shape and encourages healthy, dense growth. If desired, the plant can also be lightly pruned in late summer. Pruning too severely can affect the plant's health and discourage flowering. To prune spotted deadnettle, cut back any faded flower spikes close to the stem. Cut off any brown, wilted, or dead leaves or stems at the base. You can also trim the foliage to remove any extra branches or leave that have become overgrown.
