Overview
Lamium amplexicaule, also known as henbit dead-nettle or clasping dead-nettle, is a flowering plant that belongs to the mint family Lamiaceae. The plant is native to Europe, Asia, and North Africa, but it can now be found in many parts of the world.Description
The Lamium amplexicaule plant grows up to 30 cm in height and spreads easily via its creeping stems. It has small, heart-shaped leaves that clasp the stem. The leaves are a dark green color with a slightly toothed margin and can grow up to 4 cm long. The plant produces small, hooded flowers that range in color from pink to purple. The flowers bloom in the spring and summer.Uses
The Lamium amplexicaule plant is known to have medicinal properties, and extracts from the plant have been used to treat ailments such as bruises, cuts, and colds. It is also commonly used in landscaping and as a cover crop due to its ability to grow in a variety of soil types and tolerate shade. Additionally, the plant is known to be a food source for certain insects and wildlife.Common names
Lamium amplexicaule is commonly known by various names such as henbit dead-nettle, clasping dead nettle, henbit, red henbit, purple dead-nettle, and blue-weed. It is also known as "deadcatch" in parts of England due to the plant's ability to "catch" dead leaves that fall nearby.Light Requirements
Lamium amplexicaule typically grows in partial shade to full sun. However, it prefers a slightly shaded area, especially during the afternoon. As a result, it is common to find it growing under tall trees or shrubs where it receives filtered sunlight.
Temperature Requirements
This plant thrives in moderate temperatures ranging from 10°C – 25°C (50°F – 77°F). Lamium amplexicaule can tolerate low temperatures of up to -34°C (-30°F) but can be damaged by high temperatures above 27°C (80°F). In general, it prefers cooler climates and can be grown in most areas with mild summers and cold winters.
Soil Requirements
Lamium amplexicaule loves soils that are rich in organic matter, well-draining, and slightly acidic (pH of 6.0 – 6.5). It prefers soils that are not water-logged and has a loamy texture. When grown in heavy soils, it requires adequate amendments and drainage to prevent root rot. Before planting, it is advisable to prepare the soil by adding manure or compost to enrich the soil, and adjust soil acidity if necessary.
Cultivation
Lamium amplexicaule, commonly known as henbit, is a hardy annual weed that can grow in a wide range of soil types and light conditions.
To cultivate this plant, prepare the soil by removing any weeds or debris, and then loosen the soil with a garden fork or tiller. Scatter the seeds on the soil surface and lightly press them into the soil with a rake. Henbit can be propagated by seeds or division.
If planting in pots, use a well-draining soil mix, and make sure the pots have drainage holes.
Watering Needs
Lamium amplexicaule requires regular watering to keep the soil moist. Water the plant deeply once a week or when the top inch of soil feels dry to the touch.
Be careful not to overwater the plant, as this can lead to root rot and other problems. It's better to water deeply once a week than to give the plant small amounts of water frequently.
Fertilization
Henbit does not require heavy fertilization, as it can grow in poor soils. However, if the soil is nutrient-deficient, you can add compost or a balanced fertilizer when preparing the soil. Avoid adding too much nitrogen, as this can cause the plant to become too lush and floppy.
During the growing season, you can top-dress the soil with compost or a slow-release fertilizer. Avoid fertilizing in hot weather, as this can stress the plants.
Pruning
Lamium amplexicaule does not require extensive pruning. You can deadhead spent flowers to encourage more blooms and keep the plants looking neat. If the plants become too leggy or straggly, you can pinch back the tips to encourage branching and bushiness.
Henbit is a self-seeding plant, so be aware that pruning too heavily can reduce the number of flowers in the following year.
Propagation of Lamium amplexicaule
Lamium amplexicaule, commonly known as henbit deadnettle, is a hardy perennial plant that belongs to the mint family. Propagation of this herbaceous plant is fairly straightforward and can be done in a variety of ways.
Division
Dividing an established clump of Lamium amplexicaule is one of the easiest methods of propagation. The best time to do this is in the early spring or autumn, ideally when the plant is dormant. Using a sharp spade or garden fork, carefully separate the clump and replant the divided sections about 12 inches apart.
Cuttings
Cuttings taken from semi-ripe stems in mid-summer can also be used to propagate Lamium amplexicaule. Cut a 4- to 6-inch stem just below a leaf node, strip the lower leaves, dip the cut end in rooting hormone, and then plant the cutting in soil. Keep the soil moist and in a shaded area until roots form.
Seeds
Lamium amplexicaule also produces tiny seeds that can be sown in the early spring or fall directly into the garden bed, or started indoors in seed starting trays. Sow the seeds at a depth of ¼ inch and keep the soil moist until they germinate. Once the seedlings have grown their second set of leaves, they can be transplanted outside into their permanent location.
Disease and Pest Management for Lamium Amplexicaule
Lamium amplexicaule, commonly called henbit, is a hardy plant that can tolerate a range of growing conditions. However, it is still prone to certain diseases and pests that can cause damage to the plant. Here are some common diseases and pests that might affect Lamium amplexicaule and ways to manage them:
Diseases
1. Powdery Mildew: Powdery mildew is a fungal disease that affects many different plants, including Lamium amplexicaule. It is characterized by a white, powdery substance that appears on the leaves and stems of the plant. To manage powdery mildew, remove affected plant parts and make sure the plant has good air circulation. In severe cases, fungicides may be necessary.
2. Root Rot: Root rot is a disease caused by a fungus that affects the roots of the plant. It is characterized by the roots turning brown and becoming mushy. To manage root rot, make sure the soil is well-draining and avoid over-watering the plant. In severe cases, fungicides may be necessary.
3. Leaf Spot: Leaf spot is a fungal disease that affects the leaves of the plant. It is characterized by brown spots with yellow halos. To manage leaf spot, remove affected plant parts and avoid getting the leaves wet when watering the plant. In severe cases, fungicides may be necessary.
Pests
1. Aphids: Aphids are small, soft-bodied insects that feed on the sap of the plant. They can cause stunted growth, yellowing of leaves, and distortion of plant parts. To manage aphids, try spraying the plant with a strong stream of water to dislodge them. You can also use insecticidal soaps or neem oil to manage the infestation.
2. Spider Mites: Spider mites are tiny pests that feed on the underside of the leaves, causing yellowing and stippling. To manage spider mites, try spraying the plant with a strong stream of water to dislodge them. You can also use insecticidal soaps or neem oil to manage the infestation.
3. Slugs and Snails: Slugs and snails can eat away at the leaves and stem of the plant, causing significant damage. To manage slugs and snails, try placing copper tape or diatomaceous earth around the base of the plant. You can also create a beer trap by filling a small container with beer and placing it near the plant. The slugs and snails will be attracted to the beer and drown.
By implementing these disease and pest management strategies, you can help ensure that your Lamium amplexicaule plant stays healthy and thrives to its fullest potential.
