Generality

the verbascum genus brings together about three hundred species of perennial and annual herbaceous plants, native to Europe and Asia; some species are also widespread in Italy, even as weeds, such as V. thapsus, called the Barbasso badger. V. chaixii produces a dense rosette of dark green leaves, rough, lanceolate, even 30-40 cm long; in summer, until autumn, a thick erect stem develops from the rosette of leaves, bearing a panicle of star-shaped flowers, white or pink; there are numerous hybrids of the most varied colors, with pistils in contrasting color. They generally begin to flower from the second year after the development of the basal rosette; the stem carrying the flowers can reach 150-180 cm in height.

Plants of verbascum they are rather rustic and resistant, for this reason, they are not affected by the lower temperatures and the harsh climate of the winter season, as they can be grown outside without particular cultivation measures.
