Flora Britannica is a BBC documentary series that provides the facts,
history and folklore of Britain's native flowers and trees. Hosted by
actor Derek Jacobi ("I, Claudius"), this science and nature program
explores the medicinal properties of plants such as St. John's wort,
foxglove, and waterlilies, as well as the beauty of wildflowers like the
dandelion, henbane and pansy. Other episodes include the ancient yew
tree, the bothersome sycamore tree and the quickly vanishing elm.
