📝 Growing Notes
First year: basal rosette of large fuzzy leaves. Second year: dramatic 4, 8 ft flower spike with yellow blooms. Extremely drought-hardy once established. Prolific self-seeder; remove flower stalks to control spread. Individual flowers bloom for just one day. 'Cowboy toilet paper' , large soft leaves used in wilderness.
