Yellow Archangel Lamium galeobdolon
ABOUT
The plant commonly known as yellow archangel is recognized for its ornamental features and ground-covering abilities. It has square stems that are typical of the mint family, of which it is a part. The leaves of yellow archangel are oval-shaped, with serrated edges, and possess a striking variegation. They are often green with blotches or streaks of a silvery-white color. These leaves grow opposite each other along the stem, creating an attractive pattern. During the blooming period, typically in late spring to early summer, yellow archangel produces whorls of small, hooded flowers that are a bright yellow color and have a tubular shape. The flowers are arranged in tiered clusters that rise above the foliage, providing a splash of vivid color against the backdrop of the variegated leaves. The overall impression is of a lush, spreading plant with a lively contrast between the yellow flowers and the patterned green foliage.

WaterYellow archangel should be watered thoroughly, allowing the top inch of soil to dry out before watering again. It is generally sufficient to water once every week, but the frequency may need to increase during hot, dry spells. When watering, use about half a gallon for medium-sized pots, making sure that the water penetrates the soil and reaches the root zone without leaving the plant sitting in water, which can cause root rot. Adjust the amount based on the size of your plant; smaller plants may need less, larger ones might require more.
LightYellow archangel thrives in partial shade to full shade conditions. It is best to place the plant in a spot where it receives dappled sunlight or light shade throughout the day to mimic its natural woodland habitat. Avoid direct, intense sunlight as it can scorch the leaves and compromise the plant's health. Ideally, an east- or north-facing location works well, providing natural light without the harsh exposure of the afternoon sun.
TemperatureYellow archangel prefers temperatures between 60°F and 75°F. It is capable of withstanding short periods outside of this range, but should not be exposed to temperatures below 50°F or above 80°F for prolonged periods. The plant is hardy and can survive occasional fluctuations, making it suitable for a variety of indoor and shaded outdoor environments.
PruningPruning yellow archangel is important to maintain plant health and encourage bushier growth. Trim back the tips of the stems in the spring to promote new growth and remove any dead or damaged foliage. Pruning is also an opportunity to control the plant's vigorous spread, particularly if grown outdoors. The best time for a thorough pruning is after the plant has flowered, typically done once a year.
CleaningAs needed
SoilYellow Archangel thrives in well-draining soil high in organic matter with a slightly acidic to neutral pH between 6.0 and 7.0. A good soil mix for Yellow Archangel would consist of equal parts garden soil, peat or compost, and perlite or sand to ensure proper drainage.
RepottingYellow Archangel typically doesn’t require frequent repotting. Repot every 2-3 years to refresh the soil and accommodate growth, or when the plant has outgrown its current container.
Humidity & MistingYellow Archangel prefers moderate to high humidity levels, but it is quite adaptable. Aiming for a humidity level of 40-60% would be suitable for healthy growth.
Suitable locationsIndoor

Life cycleLamium galeobdolon, commonly known as Yellow Archangel, starts its life cycle when seeds germinate in spring, requiring a period of cold to break dormancy. Seedlings develop into vegetative plants with square stems and oval leaves, often with silvery markings. The plant reaches maturity and produces whorls of yellow, hooded flowers mainly in late spring to early summer, attracting pollinators such as bees for reproduction. Following pollination, the plant produces small nutlets as fruits, which are dispersed by various means, including animals and human activity. Yellow Archangel is also capable of vegetative reproduction through its creeping stolons, which allows it to spread and colonize new areas rapidly. As a perennial, it survives the winter in a dormant state and resumes growth in the following spring, continuing its life cycle.
PropogationPropogation time
Spring-Early Summer
Propogation: Yellow archangel, Lamium galeobdolon, is most commonly propagated through division, which is an ideal method for this rapidly spreading plant. The best time to propagate yellow archangel by division is in the spring or early fall when the plant is not in active bloom. To undertake division, gently lift a section of the plant from the soil, ensuring that the piece has some roots attached. Then, cut or tease apart sections that are at least a few inches long, with each section having an adequate amount of root structure and several leaves. Replant these divisions in prepared soil at the same depth they were growing previously, spacing them approximately 12 inches (roughly 30 centimeters) apart to allow for future growth. Proper watering and care after division will help establish the new plants successfully.
