How to care for Verbascum (Cotswold Group) Gainsborough:
Plant in full sun or light shade in well-drained soil, spacing plants to allow good airflow. Water regularly while establishing, then only during prolonged dry spells, as they dislike wet, winter ground conditions.
Deadhead spent flower stems promptly to encourage repeat flowering, and leave the basal rosette intact over winter, tidying back in spring when new growth appears.
Mullein moth caterpillars can be a problem, so pick off the insects in early June as soon as they appear. Remove faded flower spikes if you do not want them to self-seed.

Please note:
This perennial is semi-evergreen so it can lose some of its leaves in winter. In colder regions or more exposed gardens, it may lose them all, but then fresh new growth appears again in spring.
