Pruning
  • water dropWater

    Yellow Archangel should be watered sufficiently to keep the soil consistently moist but not waterlogged. During the growing season, typically from spring to fall, it may need watering once or twice a week, depending on the climate. Use a watering can or a hose with a gentle spray setting to avoid disturbing the soil or damaging the delicate foliage. It's generally a good idea to provide about one gallon of water per square yard of soil each week, although this can vary based on temperature and soil conditions. In the winter, reduce watering to prevent root rot as the plant's water requirements decrease.

  • sunLight

    Yellow Archangel thrives best in partial shade to full shade. It can tolerate some morning sunlight but should be protected from the intense afternoon sun, which can scorch the leaves. The ideal location is under the canopy of larger plants or trees, where it can receive dappled sunlight throughout the day. This will ensure the plant's variegated leaves remain vibrant without the risk of sun damage.

  • thermometerTemperature

    Yellow Archangel performs best in temperatures ranging between 60°F to 75°F. It can tolerate a minimum temperature of about 30°F and a maximum of about 80°F, though it should be noted that extreme temperatures can stress the plant. It's important to provide protection from harsh conditions such as frost or extreme heat to maintain plant health.

  • scissorsPruning

    Prune Yellow Archangel to control its spread and to remove any damaged or diseased foliage. This plant tends to grow vigorously and can become invasive, so pruning it back in early spring or after it has flowered can help maintain its shape and prevent it from overtaking neighboring plants. Cut back up to one-third of the growth to encourage denser foliage. The best time for pruning is typically after the blooming period.

  • broomCleaning

    As needed

  • bambooSoil

    Yellow Archangel enjoys moist, well-drained soil enriched with organic matter. A soil mixture consisting of peat, compost, and perlite or coarse sand is ideal for good root health. The optimal soil pH is slightly acidic to neutral, ranging from 6.0 to 7.0.

  • plantRepotting

    Yellow Archangel does not require frequent repotting and can thrive in the same container for several years. Assess the need for repotting every 2 to 3 years and repot if the plant has become pot-bound or the soil has deteriorated.

  • water dropsHumidity & Misting

    Yellow Archangel prefers average to slightly higher humidity levels but is adaptable to a range of conditions. Aim to maintain humidity around 40-50% for optimal growth, avoiding excessively dry air.

  • circleLife cycle

    Yellow Archangel 'Florentinum' (Lamium galeobdolon 'Florentinum') starts its life cycle as a seed, which germinates in spring under suitable conditions of moisture and temperature. The seedling emerges and develops into a juvenile plant, forming a rosette of leaves at the soil surface. As it matures, it grows a square stem indicative of the Lamiaceae family, and the plant spreads through rhizomes, forming a dense ground cover. In late spring to early summer, Yellow Archangel 'Florentinum' produces flower spikes with yellow hooded flowers, which are attractive to bees and other pollinators. After pollination, flowers develop into small, dry fruits called nutlets, which contain the seeds for the next generation. In harsh conditions or winter, the above-ground parts may die back, but the plant can regrow from its rhizomes the following spring.

  • sproutPropogation

    • Propogation time

      Spring to early summer

    • Propogation: The most popular method of propagating Yellow Archangel is by division. This is typically done in the spring or autumn when the plant's growth is most active. To propagate by division, gently dig up an established clump and separate it into smaller sections, making sure that each section has a good amount of roots. These sections can then be immediately replanted into moist, well-drained soil, spaced about a foot (approximately 30 centimeters) apart to allow for spreading. Water the newly planted divisions thoroughly to help establish them. Because Yellow Archangel spreads easily, this method ensures quick establishment and is ideal for gardeners looking to cover an area with ground cover efficiently.
