How to Grow and Care for Deadnettles and Lamiums
Lamium plants are clumping or spreading, semi-evergreen members of the mint family.
They are known for their beautiful silver and green variegation patterns in their
textured foliage with toothed edges that light up those dark, shaded areas
and the spires of dainty, hooded flowers that appear in late spring and early summer.
Lamiums are excellent plants for woodland areas or in your shade garden.
Some species of Lamiums may become invasive in some areas.
Growing Requirements for Lamium Plants
With the exception of L. galeobdolon 'Hermanns Pride', which appreciates a little morning sun,
Lamium plants should be grown in partial to full shade to avoid leaf scorching.
Plant your Lamiums 12"-18" apart in evenly moist, moderately rich, well drained soil.
Water thoroughly but allow soil to dry slightly between waterings.
Apply a balanced fertilizer monthly while your Lamium is actively growing.
Deadhead regularly to encourage continued blooming.
Provide protection from slugs and snails.
Yellow Archangel plants, Lamium galeobdolon are hardy in USDA zones 6-10.
They form dense 12"-24" tall clumps of deciduous, silver and green checkered foliage.
In early spring, they produce spikes of pretty, bright yellow, ¾" flowers.
Spotted Deadnettles, Lamium maculatum, are hardy in USDA zones 4-10.
They are an excellent, spreading, ground cover plant with silvery gray foliage edged with a green margin.
From April through July they produce small clusters of ¾" lavender-pink flowers that stand above the plant.
Deadnettles only grow 4"-6" tall and will spread up to 24".
They are excellent ground covers and are great when grown in planters or hanging baskets.
Deadnettles tend to languish in the heat of Summer but recover when temperatures cool in the fall.
Propagating Lamium Plants
Lamium plants can be easily propagated by layering stem tips near the ground.
Simply pin or peg a growing tip of your plant to the ground and wait
for new roots to develop before severing the new plant from the parent.
Plant crowns can be divided in the spring or fall.
Stem cuttings taken from non-flowering shoots in early summer will quickly form new roots.
Lamium reseed themselves readily, but the seeds from variegated forms will usually revert to their plain green form, so they are seldom used.
