Verbascum (Mullein)

Mullein Leaf: Benefits, Uses, and Risks

Mullein leaves have been a staple in herbal medicine for centuries. They are often used dried and can be found as part of herbal mixtures, tinctures, and teas. Traditional uses range from treating respiratory conditions to skin ailments.

Benefits

• Respiratory Relief: Mullein is well-regarded for its ability to alleviate respiratory conditions, including bronchitis, asthma, and coughs. The saponins in mullein help in loosening phlegm, making it easier to expel.
• Anti-inflammatory: Mullein leaves contain compounds with anti-inflammatory properties, making them useful for treating conditions like ear infections or hemorrhoids.
• Skin Health: Due to its anti-inflammatory and antibacterial properties, mullein is sometimes used as a remedy for minor skin irritations or wounds.
• Natural Sleep Aid: Some herbalists recommend mullein tea before bed to promote better sleep, given its potential mild sedative effects.

Uses

• Mullein Tea: Dried mullein leaves are commonly used to make a soothing herbal tea. Steep a tablespoon of dried leaves in hot water for about 10-15 minutes. Strain before drinking to remove tiny hairs that might irritate the throat.

• Mullein Oil: Mullein oil is believed to be beneficial for ear infections and earaches. To make it, fill a jar with dried mullein flowers and leaves, then pour olive oil to cover. Seal and leave in a sunny spot for 2-3 weeks. Strain the oil before using it.

Garden Design with Mullein Plants

Mullein, with its distinct appearance and history of medicinal use, can be an intriguing choice for garden design. Here’s how to incorporate it effectively:

Vertical Interest: The tall spikes of mullein provide excellent vertical emphasis in garden design. Use them as backdrops in flower beds or as standalone focal points.

Naturalistic Settings: Mullein thrives in wild or semi-wild settings like meadows or the edges of woodlands. Sowing them in such environments can create a beautiful, naturalistic feel.

Contrast: The silver-green foliage and tall yellow flower spikes offer an interesting contrast to dark-leaved plants or brightly colored blooms.

Pollinator Attraction: Mulleins are known to attract a variety of pollinators. Position them near fruit-bearing plants to boost pollination or simply to create a lively, buzzing garden space.

Gravel Gardens: Due to their drought-tolerant nature, mulleins can be a great choice for gravel gardens or xeriscaping. Their height adds dimension among other low-lying succulents or drought-tolerant plants.

Texture Play: The soft, fuzzy leaves of the mullein provide tactile interest. Pair them with glossy, hard-leaf plants or those with a different texture for a sensory treat.

Container Gardening: While traditionally a wildflower, mullein can be grown in large pots or containers. This can be an excellent way to control its spread and showcase it as a centerpiece.

Borders: Use mullein to define the borders of a garden space. Its height can serve as a natural barrier or divider, providing structure to an otherwise fluid garden.

Historical or Medicinal Gardens: If your garden has a theme, such as medieval, historical, or medicinal plants, mullein is a must-add due to its historical significance.

Tips: Mullein can self-seed quite prolifically. If you wish to control its spread, deadhead the flowers before they set seed.

Companion Plants

Mullein boasts tall spires with striking flowers, making it a distinct garden presence. When paired with suitable companion plants, the visual appeal of a garden can be significantly enhanced. Here are some ideal companion plants:

Salvia: The spiky flowers of salvia can beautifully contrast with the vertical growth of Verbascum.

Roses: The classic flowers of roses can complement the simple, tall spires of Verbascum.

Coneflowers (Echinacea): The daisy-like flowers of echinacea provide a nice contrast to the vertical growth habit of Verbascum.

Grasses: Ornamental grasses like maiden grass (Miscanthus) or feather grass (Stipa) can offer a soft, feathery backdrop or contrast to the tall, stiff spires of verbascum.

Yarrow (Achillea): With its flat-topped flowers, yarrow can create a pleasing contrast to verbascum’s vertical flower spires.

Russian Sage (Perovskia atriplicifolia): Its airy, blue flowers offer a light contrast to the often yellow blooms of Verbascum.

Daisies: Simple daisy flowers can look lovely beneath the towering spires of Verbascum.

Catmint (Nepeta): The sprawling habit and lavender-blue flowers of catmint can be a delightful contrast to Verbascum.

Lavender: Its silvery foliage and purple flowers can provide a contrasting color palette and height difference, setting off the Verbascum nicely.

Sedum (Stonecrop): Especially the taller varieties like ‘Autumn Joy’ can complement the height and structure of Verbascum.

Growing and Caring for Mullein

Soil: Mullein prefers well-draining soil. It can tolerate a variety of soil types, including poor and rocky soils, but drainage is crucial. A slightly alkaline pH is ideal.

Sunlight: Plant mullein in a location that receives full sun for at least 6-8 hours a day. They can tolerate partial shade but bloom best in full sun.

Watering: Mullein is drought-tolerant once established. Water young plants regularly until they are well-rooted. Afterward, they will need minimal watering. Ensure you don’t overwater, as mullein’s root system is susceptible to rot in soggy conditions.

Planting: You can start mullein from seed indoors about 6-8 weeks before the last expected frost. Transplant seedlings or plant direct-sown seeds about 12-18 inches (30-45 cm) apart, depending on the variety.

Fertilization: Generally, mullein doesn’t require regular feeding, especially if planted in reasonably fertile soil. If your soil is particularly poor, a light application of a balanced organic fertilizer in spring should suffice.

Pruning: Deadhead spent flower spikes to encourage more blooms. If you want the plant to self-seed, leave some flower spikes in place.

Propagation: Mullein can be easily propagated from seed. Some varieties will readily self-seed in the garden. If you’re collecting seeds, do so once the flower spikes have dried in late summer.

Overwintering: Mullein is hardy and doesn’t require special care to overwinter, though a light mulch can help protect the plant in extremely cold climates.

Pests and Diseases

Mullein is generally easy to grow and does not suffer from many pests and diseases. However, like all plants, they aren’t entirely immune. Here are some common pests and diseases that can affect Verbascum:

Spider mites: These tiny creatures suck sap from the undersides of leaves, causing stippling and yellowing. They are more prevalent in hot, dry conditions. Infestations can lead to webbing on the plant. Regularly spraying water on the undersides of leaves can deter them.

Aphids: These tiny insects suck sap from new growth, leading to distorted growth and a sticky residue that can attract other pests or lead to sooty mold. They can be washed off with water or controlled with insecticidal soap.

Powdery mildew: This fungal disease can sometimes affect Mullein, especially in humid conditions. It manifests as white, powdery spots on leaves. Improve air circulation and avoid overhead watering to prevent it. Fungicidal sprays can also help control outbreaks.

Rust: Another fungal disease that can affect mullein, rust appears as orange, yellow, or brown pustules on the undersides of leaves. Infected leaves should be removed and destroyed. As with powdery mildew, good air circulation can help prevent rust.

Leaf Spot: This is characterized by brown or black spots on the leaves, often with a yellow halo. Various fungi cause it and can be mitigated by ensuring good air circulation and avoiding overhead watering.

Root rot: If planted in poorly draining soil, mullein can suffer from root rot. This is a fungal condition where the roots decay, leading to a decline in plant health. Ensure you plant mullein in well-draining soil to prevent this issue.

Preventative Measures:

• Practicing good garden hygiene can prevent many of these issues. This includes cleaning up plant debris, spacing plants appropriately for good air circulation, and watering at the soil level instead of overhead.

• Ensure you inspect plants regularly for signs of pests or disease. Early detection often makes management much easier.
