Common Mullein (Verbascum thapsus) is a tall, resilient biennial herb valued for its striking yellow flower spikes, soft silvery foliage, and exceptional tolerance to dry, disturbed soils. Now widely naturalized across the United States, mullein thrives where many plants fail, making it a dependable choice for low-maintenance and naturalized landscapes.
In its first year, the plant forms a ground-hugging rosette of large, fuzzy leaves. During its second year, it sends up a dramatic flowering stalk that can reach up to 7 feet tall, lined with clusters of bright yellow blooms from early summer through early fall. These showy flowers attract pollinators and bring bold vertical structure to wild gardens, meadows, and open landscapes.
Common Mullein is drought tolerant once established and performs best in full sun with well-drained soil. While it produces abundant seeds, it typically germinates only in open, sunny ground and is easy to manage in cultivated areas.

Mullein produces many seeds, but it is not aggressively invasive. Seeds usually germinate only in open, sunny soil and are easy to manage in gardens.
Is mullein easy to grow?
Yes. It is very easy to grow, especially in full sun with well-drained soil and minimal watering.
Can mullein be grown in containers?
It can be started in containers, but due to its deep taproot and height, it performs best when transplanted into the ground.
