Spotted Deadnettle Lamium maculatum Golden Anniversary = 'Dellam' (PBR) (v)

Water

Spotted Dead Nettle, preferably, requires consistent moisture but not soggy soil. Water it deeply once a week, ensuring about 1-2 gallons per square yard, depending on the weather conditions. During the hotter seasons or periods of drought, increase the frequency to maintain moist soil, but be cautious to avoid overwatering which may lead to root rot. In cooler seasons or during rainfall, reduce watering but do not allow the soil to completely dry out. It's critical to provide water at the base of the plant to keep the foliage dry and prevent any fungal issues.

Light

Spotted Dead Nettle thrives in partial shade to full shade conditions. It should be placed in a location that receives filtered sunlight or a spot with morning sun and afternoon shade. Avoid exposing it to the full afternoon sun, as this can scorch the leaves and stress the plant. Therefore, the ideal spot for this plant would be under the canopy of open trees or on the north side of buildings where it can receive ample light without direct, intense exposure.

Temperature

Spotted Dead Nettle grows best in temperatures that range between 55 to 75 degrees Fahrenheit. It can withstand minimum temperatures down to about 30 degrees Fahrenheit but should be protected from frost. The plant can survive up to a maximum of about 80 degrees Fahrenheit, but it is essential to provide adequate moisture and shade if the temperatures climb higher. Ensuring that it's planted in a spot with suitable temperature conditions is integral to its growth and overall health.

Pruning

Deadheading Spotted Dead Nettle is not necessary, as it does not significantly encourage more blooms. However, light pruning can be done to maintain its shape and remove any tattered leaves or stems. The best time to prune is in late winter or early spring before new growth begins. Annually cut back the foliage by one-third to rejuvenate the plant and promote fresh, vigorous growth.

Cleaning

As needed

Soil

Spotted Deadnettle thrives in well-draining, rich soil with a pH ranging 6.0 to 7.0. For best results, use a mix of loamy soil, compost, and a small amount of sand or perlite to ensure proper drainage. Mulch can help retain moisture and suppress weeds.

Repotting

Spotted Deadnettle does not typically require frequent repotting. It should be repotted every 2-3 years or when it has outgrown its current container, which is evident when roots start to circle the pot or poke out of the drainage holes.

Humidity & Misting

Spotted Deadnettle prefers average to high humidity levels but is adaptable to lower humidity environments. It typically thrives outdoors where the humidity is naturally regulated, but can also do well indoors if not placed in an excessively dry area.

Suitable locations

• Indoor

  Place in bright, indirect light and keep soil moist.

• Outdoor

  Plant in partial shade; keep soil moist but well-drained.

• Hardiness zone

  3-8 USDA

Life cycle

Spotted Deadnettle 'Golden Anniversary' ('Dellam') begins its life cycle when the seeds germinate in early spring, given suitable warm and moist soil conditions. Once sprouted, the seedlings grow rapidly, with the characteristic silver-spotted, yellow-green foliage emerging. As a perennial, the plant establishes a strong root system and will grow and expand each year through vegetative propagation, such as stoloniferous growth. Flowering occurs from late spring to early summer, producing clusters of pink to purple flowers that attract pollinators. After flowering, seeds are set, which may drop and give rise to new plants the following season. Throughout the winter, the plant may die back partially but typically re-sprouts from the roots as temperatures rise in the spring.

Propogation

• Propogation time

  Spring to Summer

• Propogation: Spotted deadnettle 'Golden Anniversary', also scientifically known as Lamium maculatum 'Dellam', is commonly propagated through stem cuttings. The best time to take these cuttings is in the spring or early summer when the plant's growth is most vigorous. To propagate, choose a healthy stem and cut a 4 to 6-inch (approximately 10 to 15 cm) length, making sure that several leaf nodes are included. Remove the leaves from the lower half of the cutting and dip the cut end into rooting hormone powder to encourage root growth. The cutting should then be planted in a pot filled with moistened potting mix, sand, or vermiculite. Covering the pot with a plastic bag can help maintain humidity levels, which is beneficial for root development. Roots typically develop within a few weeks, after which the new plant can be transplanted into the garden.
