The Life Cycle of a Mullein Plant

During the first year of growing, the leaves of the plant emerge from the crown at the soil surface. In the second year, the plants develop a flower stalk. Mullein has alternate leaves, which decrease in size towards its top.

The plant produces yellow flowers. It might also grow white flowers, but this happens rarely. They attract several insects, such as butterflies, bees, and flies.

The insects help in cross-pollination. In case there are no insects, the plant self-pollinates itself.

At maturity, mullein fruit separates into two halves.

After flowering, the plant dies.

The seeds of mullein remain viable for many years. Hence, it is difficult to eradicate the plants from a particular area entirely.

Only the seeds exposed to light will germinate. Those in darkness will remain dormant.

How to Get Rid of Mullein Plants?

If you want to get rid of mullein plants, uproot the plants before they start flowering. Avoid disturbing the soil. Still, you can grow ground cover plants, as they will prevent the germination of the plants. If the infestation of the plant is very dense, use herbicides. Although, they might not be as effective since the hairy surface of the plant hinders absorption.

Origin of Mullein

Mullein was first introduced to the United States in the 1700s. It was used as a chemical substance, poisonous to fish. Since it grows in several environmental conditions, the plants spread quickly in the United States. The plant is common to Mediterranean countries.
