    Fast-Growing, Shade-Tolerant, Easy-Care Groundcover

    • Shade-Loving Beauty: Tired of struggling to find plants that thrive in the shade? Yellow Archangel flourishes in low-light conditions, brightening up those dim corners of your garden.
    • Fast-Growing Groundcover: Quickly fills in bare areas, creating a lush carpet of silvery-green foliage and cheerful yellow flowers.
    • Low-Maintenance: Once established, Yellow Archangel is remarkably easy to care for, requiring minimal watering and attention. It is drought-tolerant once established.
    • Deer and Rabbit Resistant: Enjoy your garden without worrying about browsing animals! Yellow Archangel is generally unappealing to deer and rabbits.
    • Beautiful Variegation (for variegated types): Many cultivars boast striking variegated leaves with silver or white markings, adding extra visual interest even when not in bloom.
    • Attractive Flowers: Bright yellow, hooded flowers appear in late spring to early summer, attracting pollinators (though it is not a major nectar source).
    • Suppresses Weeds: Its dense growth habit helps to naturally suppress weed growth, saving you time and effort.
    • Erosion Control: Its spreading roots help stabilize soil on slopes and banks.

    Important Note about Invasiveness:

    • Know Your Region: Lamiastrum galeobdolon can be invasive in some regions, particularly in the Pacific Northwest of the USA and parts of Europe. Before planting, check with your local extension office or garden authorities to ensure it is not considered invasive in your area. Always plant responsibly. Consider contained plantings (e.g., in pots, raised beds, or areas bounded by sidewalks) to limit spread.

    Light: Prefers partial to full shade. Can tolerate some morning sun, but avoid intense afternoon sun, which can scorch the leaves.

    Soil: Adaptable to a wide range of soil types, but prefers moist, well-drained soil rich in organic matter. Amend heavy clay soil with compost or other organic material to improve drainage.

    Water: Water regularly, especially during the first growing season, to establish a strong root system. Once established, it is relatively drought-tolerant but will perform best with consistent moisture. Avoid overwatering, which can lead to root rot.

    Planting:

    • When: Spring or fall is the ideal time to plant.
    • How:
      • Dig a hole slightly larger than the root ball.
      • Gently loosen the roots if they are pot-bound.
      • Place the plant in the hole so that the top of the root ball is level with the surrounding soil.
      • Backfill the hole with soil, 1 firming gently.
      • Water thoroughly.
    • Spacing: Space plants 12-18 inches apart, depending on the cultivar and desired coverage speed.

    Fertilizing: Generally, Yellow Archangel does not require much fertilizer. A light application of compost or a balanced, slow-release fertilizer in early spring can be beneficial, especially in poor soils.

    Pruning:

    • Prune back stems as needed to control spread or maintain a desired shape. You can shear the plant back after flowering to encourage bushier growth. Remove any dead or damaged foliage.
    • To prevent unwanted spread (crucially important): Remove flower stalks before they set seed. This is the primary way the plant spreads aggressively. Deadheading will prevent self-seeding.

    Propagation:

    • Easily propagated by division in spring or fall. Simply dig up a clump and separate it into smaller sections, each with roots and shoots.
    • Stem cuttings can also be taken in spring or summer.

    Winter Care: In colder climates, Yellow Archangel may die back to the ground in winter. It will typically re-emerge in spring. A layer of mulch can help protect the roots in very cold regions.

    Pests and Diseases:  Generally, pest and disease resistant. Slugs and snails may occasionally nibble on the foliage, but this is usually not a significant problem.

    Container Growing: Yellow Archangel can be successfully grown in containers. Choose a pot with drainage holes and use a well-draining potting mix. Container growing is a good way to control its spread.

    Plant Lamiastrum in moist, well-drained, rich soil in partial shade for optimum performance. Once established, it tolerates some drought. Deer resistant, groundcover, great in hanging baskets, window boxes or as a filler plant.

    Lamiastrum galeobdolon, commonly known as yellow archangel or golden dead-nettle, is a perennial groundcover that offers gardeners an attractive and low-maintenance option for shady areas. This member of the mint family (Lamiaceae) is native to shaded woodlands, copses, and thickets throughout much of Europe and western Asia. In New England, it can be found in the edges of forests and human-caused or disturbed habitats. While it can be an aggressive spreader, with proper understanding and care, yellow archangel can be a valuable addition to gardens.

    Yellow archangel is recognized by its spreading habit and distinctive foliage. It grows up to 12–24 inches tall (30–60 cm) and will spread indefinitely. The leaves are opposite, ovate to rounded, with toothed edges and a pointed tip. They are typically medium to dark green, but many cultivated varieties have attractive silver markings. The leaves are aromatic when crushed. The small, yellow flowers bloom for a few weeks in mid-spring, with a few flowers produced sporadically later in the year, adding a touch of brightness to shady gardens. Flowers are in whorls of 4 to 10 at the top of the plant and at leaf axils in the upper half of the stem. Individual flowers are ¾ to 1 inch long, light lemon yellow, irregular with 2 lips at the end of a tube up to 3/8 inch long. The broad upper lip is rounded like a hood, densely covered in short hairs, and fringed with longer hairs all around the edge. The lower lip has 3 spreading lobes all about the same size, the center lobe streaked with darker orange-yellow.

    Growth Habit Yellow archangel spreads by creeping stems (stolons) that root at the nodes, allowing it to form a dense mat of foliage. This plant trails along the ground by creeping runners (stolons) as a ground cover, but will climb in an almost vine-like manner over low-growing vegetation and tree stumps, typically rooting in the ground at the nodes when they come in contact with the soil. It can also spread by stem fragments and seed. It spreads by stem and root fragments and can grow up to 3 feet (1 meter) per year, giving it a competitive advantage over other plants. This vigorous growth habit makes it an effective groundcover, but it can also become invasive if not managed properly. It can grow up to 12–24 inches tall (30–60 cm) and will spread indefinitely.

    Hardiness Zones Yellow archangel is hardy in USDA zones 4 to 9, making it suitable for a wide range of climates. It can tolerate temperatures as low as -40°F (-40°C). It is tolerant of a variety of urban conditions, including air pollution.

    Ideal Growing Conditions One of the key advantages of yellow archangel is its adaptability to a wide range of growing conditions. It thrives in both full shade and full sun, as long as it receives adequate moisture. It also tolerates various soil types, including clay, making it a versatile choice for different garden environments.

    Sunlight Requirements While yellow archangel prefers shade, it can tolerate full sun if the soil moisture is adequate. However, in hot climates, it is best to provide some shade to prevent the leaves from scorching.

    Soil Type Yellow archangel is adaptable to a wide range of soil types, including clay soil. While it tolerates most soils, it prefers a light calcareous soil.

    Moisture Requirements Yellow archangel prefers moist soil but can also tolerate dry shady sites and drought. In dry climates, regular watering may be necessary, especially during hot weather.

    Planting and Care

    Planting When planting yellow archangel, space the plants about 14 inches apart. Water regularly during the first growing season to help the plants establish.

    Note: This plant is prohibited in both WA and OR states.

    Care Yellow archangel requires minimal care. It can be sheared back to 4 to 6 inches if it becomes leggy or cut back to new leaves at the base of the plant in midsummer. It can be divided as needed in spring or fall. Will self-seed, but seedlings may not grow true to parent.

    Propagation Yellow archangel can be easily propagated through division or stem cuttings. Division is best done in spring or fall. Simply dig up a clump of the plant and carefully separate it into smaller sections, ensuring each section has roots attached. Replant the divisions at the same depth as the original plant. Stem cuttings can be taken in spring or summer. Cut a 4- to 6-inch section of stem and remove the lower leaves. Insert the cutting into a pot filled with moist potting mix and keep it in a shady location. Roots should develop within a few weeks.

    Common Problems and Pests Yellow archangel is generally pest-free and disease-resistant. However, it is important to be aware of its potential to become invasive. Yellow archangel escapes from residential plantings, becoming very invasive and forming dense mats of groundcover vegetation. This plant outcompetes native species and does not provide adequate food or cover for wildlife. To prevent it from spreading, remove any unwanted plants by hand, making sure to remove all root fragments. For larger infestations or where hand-pulling is not feasible, herbicides may be necessary. Always follow the manufacturer's instructions carefully when using herbicides.

    Planting Lamiastrum is a breeze, thanks to its adaptability and resilience! Here is how you can get started:

    Choosing the Right Time and Location:

    • Timing: The best time to plant Lamiastrum is in spring or fall when the temperatures are mild. In mild climates, you can even plant in winter. Avoid planting during extreme heat or frost.
    • Location: Lamiastrum thrives in partial to full shade, although some varieties like 'Hermanns Pride' can tolerate light morning sun. Avoid full sun in hot climates to prevent leaf scorch.

    Preparing the Soil and Planting:

    • Soil: Lamiastrum prefers well-drained, moderately fertile soil. If your soil is heavy clay, amend it with compost or well-rotted manure to improve drainage.
    • Planting: Dig holes slightly larger than the root ball of your Lamiastrum plants. Space them according to their mature size: about 12-18 inches apart for standard varieties and 8-12 inches for smaller varieties. Gently remove the plants from their containers and loosen the roots if tightly bound. Place them in the holes and backfill with soil, tamping it down gently. Water thoroughly to settle the soil around the roots.

    Additional Care Tips:

    • Watering: Water regularly, especially during the first year of establishment, to keep the soil moist but not soggy. Once established, Lamiastrum is somewhat drought-tolerant and only needs occasional watering during dry spells.
    • Mulching: Apply a layer of mulch around the base of your plants to retain moisture, suppress weeds, and regulate soil temperature.
    • Fertilizing: Lamiastrum does not require much fertilizer but can benefit from a light application of balanced fertilizer once or twice a year during the growing season.
    • Maintenance: Lamiastrum is relatively low maintenance. You can deadhead spent flowers to encourage repeat blooming, and occasionally trim back leggy stems to maintain a neat appearance.

    Propagation:

    If you would like to expand your Lamiastrum collection, good news! It is easy to propagate:

    • Division: Divide established clumps in spring or fall, ensuring each division has healthy roots and shoots. Replant divided sections in prepared soil.
    • Stem cuttings: Take 4–6-inch stem cuttings in early summer and remove the bottom leaves. Dip the cut end in rooting hormone and plant in a pot with moist potting mix. Place in a bright, indirect location and keep the soil moist. Once rooted, transplant to your desired location.
    • Layering: Bend a long stem down to the ground and cover a portion with soil, leaving the tip exposed. Roots will form at the buried section, and you can detach the rooted section later to create a new plant.

    By following these simple steps, you can enjoy the lush foliage and cheerful blooms of Lamiastrum in your garden for years to come!

    Bonus Tip: Lamiastrum attracts pollinators like bees and butterflies, making it a valuable addition to a pollinator-friendly garden.

    I hope this information clarifies the situation around Lamiastrum and helps you make informed decisions about planting it in your garden.

    The best time to divide Lamiastrum depends on your climate and personal preferences, but there are two main windows that are generally optimal:

    Early Spring:

    • Ideal if you live in a cooler climate: In areas with mild winters and early springs, dividing Lamiastrum in early spring gives the new divisions plenty of time to establish before the heat of summer.
    • Benefits from cool, moist soil: Early spring tends to offer cooler and more consistently moist soil, which helps the divided plants recover and root more efficiently.
    • Avoids potential frost damage: Dividing late in spring carries a slight risk of frost damage to the new divisions, especially in colder climates.

    Early Fall:

    • Great in warmer climates: For warmer regions with mild autumns and winters, dividing in early fall can be advantageous.
    • Warm soil encourages root growth: The warm soil temperatures of early fall can actually stimulate root growth and establishment in newly divided plants.
    • More established before winter: Dividing early in fall allows the new divisions to become relatively established before winter arrives, giving them a better chance of thriving through the colder months.

    Additional factors to consider:

    • Blooming period: Avoid dividing while your Lamiastrum is in full bloom. Wait until after flowering has finished for less stress on the plant.
    • Plant health: Choose healthy, mature clumps for division. Weak or diseased plants may struggle to recover from the splitting process.
    • Weather conditions: Avoid dividing during periods of extreme heat or drought, as this can be stressful for the plants. Choose a day with mild temperatures and good moisture levels.

    Ultimately, the best time to divide your Lamiastrum depends on your specific circumstances and goals. Consider your climate, the blooming period, plant health, and weather conditions to determine the most suitable window for division in your garden.

    I hope this information helps you choose the optimal time to divide your Lamiastrum and ensure they flourish in your garden!
