Mullein is a good beginner forager plant. Common mullein is a widespread, easy-to-identify plant in all seasons, and is commonly found on disturbed soils. It has a tall stalk that grows up straight, up to seven feet tall surrounded at the base by a rosette of velvety gray-green leaves. If you just find the rosette of leaves, this indicates where next summer’s stalk and flowers will bloom, as mullein is a biennial and does not flower or go to seed until the second year. People use mullein for asthma, bronchitis, pneumonia, cold and flu, and many other conditions.
