About Wavy-leaf mullein
Verbascum sinuatum, commonly known as Wavyleaf Mullein, is a biennial or short-lived perennial plant characterized by its large, wavy, and pubescent basal rosettes, from which a tall, branched flower stalk emerges, bearing numerous yellow flowers. It is an excellent choice for naturalistic gardens, rockeries, or sunny borders, adding vertical interest and a rustic touch. Its spectacular bloom attracts pollinators.

Care tips
This plant thrives in full sun exposure and well-drained soils, even poor or calcareous ones, as it is highly adaptable. Watering should be moderate, allowing the substrate to dry out completely between waterings, and it is quite drought-tolerant once established. A common mistake is overwatering, which can lead to root rot. It does not require frequent fertilization; poor soil is often preferable.
