ERYNGIUM
ERYNGIUM
Commonly known as Chilean sea holly, Eryngo
Genus of 230 species annuals, biennials and deciduous and evergreen perennials, some very decorative.
Those from dry areas of Europe, northern Africa, Turkey, central Asia, China and Korea usually have tap roots. Those from wetter areas and marshy grassland in Mexico, Brazil, Argentina and warm-temperate regions of North, Central and South America have fibrous roots.
Most have spiny leaves and thistle-like flowers. They are striking plants for naturalizing and can be dried for arrangements if flowers are cut before becoming fully open.
Many species have been used for food and medicine.
All attract bees and other insects.
UK native E. maritimus, Sea holly is found in sand dunes and on shingle sea shores. The roots used to be candied with sugar and orange flower water and used as an aphrodisiac.
Field eryngo, E. campestre, a native perennial of dry, grassy places is rare and found only in the south of England.
