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.

Whether Lamiastrum is considered invasive depends on your location and perspective. Here is a breakdown:

Generally:

  • Lamiastrum galeobdolon, the only recognized species, is not listed as a federally invasive plant in the United States.
  • However, it can be invasive in certain regions, particularly in the Pacific Northwest and other areas with similar climates.

Invasive potential:

  • Lamiastrum spreads rapidly by both stolons (runners) and seeds, readily forming dense mats that can outcompete native plants.
  • It thrives in shade and moist conditions, making it a threat to undisturbed forest understories and natural areas.
  • Its dense growth can suppress the regeneration of native trees and shrubs, disrupting natural ecosystems.

Regional considerations:

  • In the Pacific Northwest, Lamiastrum is listed as a noxious weed in several states. It is considered a serious threat to native biodiversity in these regions.
  • Outside of the Pacific Northwest, Lamiastrum may still become invasive in specific habitats like undisturbed natural areas.
  • It is always advisable to check with local authorities or gardening resources to confirm the invasive status of Lamiastrum in your area.

Alternatives:

  • If you are concerned about the invasive potential of Lamiastrum, consider alternative shade-loving groundcovers.
  • Native plants in your region are excellent choices, as they support local ecosystems and attract native pollinators.
  • Other non-invasive groundcovers like Ajuga reptans (Bugleweed) or Vinca minor (Periwinkle) can be good alternatives.

Here are some additional factors to consider:

  • Cultivar variation: Some Lamiastrum cultivars, like 'Mont Blanc,' are less vigorous and invasive than others.
  • Planting location: Avoid planting Lamiastrum near natural areas or sensitive habitats.
  • Containment strategies: If you choose to plant Lamiastrum, use physical barriers like edging to control its spread.

It is important to be responsible when considering plants that may have invasive tendencies. Carefully researching Lamiastrum's invasive potential in your specific area and choosing alternatives, if necessary, will help protect your local ecosystem and ensure responsible gardening practices.

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!
