Can You Grow Mullein Indoors?

Absolutely! While Mullein (Verbascum thapsus) is typically found in the wild, it can thrive indoors as well. This herb’s adaptability to different growing conditions makes it a perfect addition to your indoor garden.

Can You Grow Mullein in a Pot?

Yes, you can grow Mullein in a pot. In fact, it’s a practical choice for indoor gardening, allowing you to control the plant’s environment and ensure it doesn’t overtake your garden. Choose a pot that’s at least 12 inches deep and provides good drainage to prevent waterlogged roots.

How to Grow Mullein from a Seed

What You’ll Need:

  • Mullein seeds
  • A well-draining pot or container
  • Potting soil
  • Sunlight or grow lights

Step-by-Step:

  1. Fill your pot with well-draining potting soil. Moisten the soil slightly.
  2. Plant the Mullein seeds on the soil’s surface, but don’t bury them. Gently press them down.
  3. Place the pot in a sunny window or under grow lights. Mullein loves sunlight and requires at least 6-8 hours a day.
  4. Keep the soil consistently moist but not waterlogged. You can use a spray bottle to mist the soil’s surface.

Growing Mullein from cuttings is less common but still doable.

What You’ll Need:

  • A healthy Mullein plant
  • Clean, sharp scissors or pruning shears
  • A well-draining pot
  • Potting soil

Step-by-Step:

  1. Take a 3-4 inch cutting from a healthy Mullein plant, making the cut just below a leaf node (where leaves meet the stem).
  2. Remove the leaves from the lower half of the cutting.
  3. Plant the cutting in a pot with well-draining potting soil.
  4. Keep the soil consistently moist and place it in a sunny location.

What a Mullein Plant Looks Like

Mullein is a unique and easily recognizable plant. It produces a rosette of large, soft, velvety leaves in its first year, which can reach 2 feet in length. In the second year, it sends up a tall flower spike, which can grow up to 6 feet or more. The flowers are small, yellow, and densely packed on the spike, creating a striking appearance.

How Long It Takes to Grow Mullein Indoors

Mullein is a biennial plant, meaning it completes its lifecycle in two years. In its first year, it primarily develops leaves and roots, and in the second year, it flowers and produces seeds. You can typically expect your indoor Mullein to flower in its second year, so patience is required. However, the large, velvety leaves in the first year make it a beautiful and useful addition to your indoor garden.
