yellow archangel

Lamium galeobdolon subsp. montanum 'Florentinum'

The yellow archangel (Lamium galeobdolon subsp. montanum 'Florentinum') is a low-growing, evergreen perennial perfect for brightening up the shade garden. Primarily grown for its dense carpet of heart-shaped, yellow-splashed variegated foliage, the plant also produces tubular shaped flowers from early summer through midsummer, which attract pollinators like bees and butterflies. It works as a great groundcover for shady areas, and its flowers create a textural and colorful contrast to woody perennials or conifers. Deer and rabbits rarely bother it so it can provide you with years of enjoyment in one of the trickier parts of your garden.

watering

For the yellow archangel plant, water when the soil begins to feel dry to the touch, about once a week. Make sure the soil is moist but not soggy, as too much water can cause root rot. If the plant is in a container, water enough to moisten the soil, and then wait until the top couple inches of the soil feel dry before watering again.

sunlight

Yellow archangel plants prefer full sun and partial shade. They prefer an area that gets at least 6 hours of sun per day. During the summer months, the plants can tolerate up to 8 hours of sunlight when temperatures are cooler. It’s also important not to expose them to too much direct sun in the middle of the day, as this can cause the leaves to burn and become discolored. Direct sun during the other parts of the day should be fine.

pruning

Yellow archangel should be pruned regularly in order to promote healthy growth and control its shape. The best time for pruning is late winter or early spring, before new growth begins. Pruning helps the plant look its best and helps keep it under control. Start by removing any dead or damaged branches and any growth that is blocking pathways or views. Thin out congested branches and cut back any wayward or unruly stems to keep the shape tidy and balanced. The overall pruning should be light, no more than 1/3 of the overall plant should be removed. This will promote more blooms, reduce overcrowding, and promote air circulation.
