Dark Mullein is a tall biennial/short-lived perennial, wild flowering plant producing stems of yellow flowers with purple stamens from June to October. Reaches about 1m high. Leaves are hairy rather than ‘woolly’ as is the case for Common Mullein (Verbascum thapsus). Prefers a well-drained soil and sunny position. Valuable plant for wildlife - the flowers are a great source of pollen and nectar for a wide range of insects, particularly bees. Birds such as the goldfinch feed on the large number of small seeds and over-wintering insects can hibernate in the dead flowering stems. Mullein tea is a traditional treatment for respiratory problems such as asthma, bronchitis and chest colds. Leaf tea is slightly bitter. Using the flowers produces a sweeter flavour.
