Tripolium pannonicum
''Tripolium pannonicum'', called the sea aster and often known by the synonyms ''Aster tripolium'' or ''Aster pannonicus'', is a flowering plant, native to Eurasia and northern Africa,〔(USDA, ARS, National Genetic Resources Program. Germplasm Resources Information Network - (GRIN). National Germplasm Resources Laboratory, Beltsville, Maryland. )〕〔 that is confined in its distribution to salt marshes, estuaries and occasionally to inland salt works.
It is a perennial growing up to 50 cm tall with fleshy lanceolate leaves and purple ray florets flowering from July to September. The plants tend to be short-lived and populations need significant new recruitment each year from new seedlings.
There are rayed as well as rayless varieties and only the former have long blue or white florets. The rayless form is yellow. The plant flowers well into autumn and hence provides a valuable source of nectar for late-flying butterflies such as painted lady and red admiral.
