About Common mullein

Verbascum thapsus, commonly known as Great Mullein, is a striking biennial plant renowned for its tall, sturdy flower spike adorned with numerous small yellow blooms. Its large, soft, velvety basal leaves form a distinctive rosette. It is ideal for cottage gardens, naturalized meadows, or as a focal point in perennial borders, providing dramatic verticality and wild appeal.

Native range

Europe and temperate Asia

Care tips

Great Mullein thrives in full sun and well-drained soils, even poor or rocky ones, making it highly drought-tolerant once established. It requires minimal watering, only during extreme dry spells, as excessive moisture can lead to root rot. Avoid heavy, clayey soils that retain too much water, and do not over-fertilize, as this can weaken the flower stalk. This plant readily self-seeds, so allow its seeds to drop to ensure its presence in future years.
