Tragopogon pratensis L. Asteraceae Goats beard, Salsify, Jack-go-to-bed-at-noon. Distribution: Europe and North America. This is the Tragopogion luteum or Yellow Goats-beard of Gerard (1633) who recommended them boiled until tender and then buttered as being more delicious than carrots and parsnips and very nutritious for those sick from a long lingering disease. Boiled in wine they were a cure for a 'stitch' in the side. In the USA children collect the milky sap onto a piece of glass and, when dry, chew it as bubble-gum. The name 'Jack-go-to-bed-at-noon' referes to the flowers which close at noon and the spherical radiation of seed plumules which then appear. Salsify is now applied as a name for T. porrifolius and Scorzonera hispanica. Photographed in the Medicinal Garden of the Royal College of Physicians, London. Dr Henry Oakeley.
