High humidity,prolonged leaf wetness, and cool weather favor the development of Downy Mildew diseases. Once infection is established, sporangiophores emerge from the stomata on leaf undersides and sporangia are easily spread by splashing water,wind, or handling.
Lamium galeobdolon can be toxic.
Lamium orvala and its cultivars tend to bloom for a more modest six weeks from spring to early summer, but blooms densely populate the leaf axils for the majority of the time.
The genus Lamium is comprised of several dozen species of annuals and perennials from Europe to Asia, and the Mediterranean and North Africa. Members of the mint family, these plants have the typical square stems, toothed leaves, and spreading habit.
Lamium 'Roseum' is known for attracting bees. It has nectar/pollen rich flowers.
If you are only going to take a small number of cuttings i would strike the roots of lamium in water. Still store them in an area out of direct light. Roots in both mediums will develop quickly. You should have a good root system Read more
Choosing a Location. Lamium tolerates some sunlight, but it grows best in partial to full shade. In full sun, particularly in hot climates, the leaves become scorched, brown and withered. Lamium thrives in soils with a pH between 6.0 and 7.0 so if your soil Read more
Deadnettle (Lamium) genus has three edible plants in it that are found in eastern North America. The Henbit (Lamium amplexicaule), the Purple Deadnettle (Lamium purpureum), and the White Nettle (Lamium album). Each one has a section of its own below.
Space the plants 3 to 4 inches apart to allow them to spread comfortably. Plant lamium in a line or staggered in a bed, according to your garden plan.
History and Origin: Lamium is a genus of around 40-50 species within the family Lamiaceae and is native to Europe, Asia and northern Africa. The name Lamium comes from the Greek word 'lamia' meaning 'devouring monster' which refers to the shape of the flowers that Read more
They are self-pollinating because the corollas do not open to pollinators. They are often produced especially at cool times of year when there are no pollinators around.
Plant yellow-flowered lamium in a shady spot during fall. Plant white and purple-flowered species in full sun during spring.
New Lamium plants spread more rapidly when they are pruned to encourage branching. You can pinch plants back to a leaf joint or cut the stems with bypass pruners to encourage shoots from the cut location. Clip the new growth back to a leaf joint, Read more
Getting Started. Most people grow lamium from a few nursery plants. The plant spreads quickly and within a year, four or five plants can fill in a space of 40 square feet or more.
Dig a 2- to 3-inch hole in the soil using a small garden shovel. Place the plant in the hole. Sweep the dirt around the base of the plant. Lamium does not thrive when planted too deeply.
Lamium maculatum grows best in part shade (especially for silver types which often need more light to maintain their color) or shade in moist, humus-rich, well-drained soil, but in our climate will even grow in full sun.
The small clusters of flowers are usually pink, white or purple, and appear from spring through late summer. Lamium is a versatile plant, hardy in U.S.D.A. plant hardiness zones 4 through 8. In zones 6 through 8, it remains evergreen most of the year.
Edible Parts Leaves and flowers can be used. They can be used to make an herbal tea. Add leaves and flowers into a salad, stews or soups. Chopped up finely, they can be added to mashed potatoes.
