Quick facts

About Hoary mullein

Verbascum pulverulentum, commonly known as Hoary Mullein, is a striking biennial or short-lived perennial plant native to Europe. It is characterized by its tall, branching flower spikes, covered in dense white-tomentose foliage, which can reach up to 2 meters in height, looking spectacular in sunny borders and naturalistic gardens. Its bright yellow flowers, often with purple centers, attract pollinators and add dramatic verticality to the landscape.

Europe and temperate Asia

Care tips

It prefers full sun exposure for optimal growth and abundant flowering. Watering should be moderate, allowing the substrate to dry out between waterings, as it tolerates drought well once established. It requires well-drained soil, preferably poor or moderately fertile, as overly rich soils can promote excessive foliage growth at the expense of flowering. Avoid excessive soil moisture, which is the most common mistake and can lead to root rot.
