Verbascum nigrum aka Black Mullein

If you're looking for a plant that offers a moderate level of challenge, Black Mullein is a great choice to test your gardening skills.

Black Mullein should be watered regularly, allowing the soil to dry out between waterings.

Black Mullein loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Black Mullein requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Dark Mullein is always in the right place to thrive.

There is no verified data on the toxicity of this plant in the records of Ploi. If any person, including yourself, a family member, or a pet, consume plant material with an uncertain toxicity level, it is advisable to seek the advice of a healthcare expert.

Repotting the Black Mullein should be done either when it has doubled in size or on a yearly basis, whichever occurs sooner. Fresh potting soil with all the required nutrients, refreshed annually, will provide the plant with all the necessary sustenance, making the use of fertilizer unnecessary. Keep in mind that plants receive their energy from the sun, not fertilizer.

Black Mullein’s native range is Europe, including Britain, from Scandanavia south and east to Spain, Siberia, Macedonia, Caucasus.
