"Digitalis lanata" is a biennial or perennial growing from a woody, horizontal rootstock. There is a tidy rosette before the spike goes up, and it is neatly arranged around the purple-tinged stems. The plant commonly forms a single, upright, more or less uniformly leafy stem that is partly ascending at the base. The plant send up these stems and flowers in usually in its second year. The stems are 0.3 to 0.6 meters in height, or about 13 to 26 inches.
