Aegopodium podagraria
''Aegopodium podagraria'' L. commonly called ground elder, herb gerard, bishop's weed, goutweed, gout wort, and snow-in-the-mountain, and sometimes called English masterwort,〔(Goutweed (''Aegopodium podagraria'') ) Mrs. Grieve's "A Modern Herbal" at Botanical.com]〕 and wild masterwort,〔 is a perennial plant in the carrot family (Apiaceae) that grows in shady places. The name "ground elder" comes from the superficial similarity of its leaves and flowers to those of elder (''Sambucus''), which is unrelated. It is the type species of the genus ''Aegopodium''. This species is native to Eurasia, and has been introduced around the world as an ornamental plant, where it occasionally poses an ecological threat as an invasive exotic plant. ==Description== ''A. podagraria'' is perennial, growing to a height of 100 cm with rhizomes. The stems are erect, hollow and grooved. The upper leaves are ternate, broad and toothed. The flowers are in umbels, terminal with rays 15 - 20, with small white flowers, the fruits are small and have long curved styles.〔Webb, D.A., Parnell, J. and Doogue, D. 1996. ''An Irish Flora.''

ISBN 978-185918-4783〕 the flowers are visited by many types of insects, thus being characterised by a generalised pollination system.
