车前叶蓝蓟（学名：Echium plantagineum）是蓝蓟属的一个物种，原产于欧洲西部和南部（从英国南部往南至到伊比利亚，往东至克里米亚）、非洲北部、和亚洲西南部（往东至格鲁吉亚）。该物种也被引入到澳大利亚和南非，是当地入侵植物。由于其嫩枝上的双稠吡咯啶类生物碱含量高，对于放牧的家畜有毒，尤其是马等只有简单消化系统的动物。毒素在肝脏沉积导致死亡。

这是一种一年生植物，可长至20-60厘米高，叶子至14厘米长，粗糙有毛。花为紫色，长15-20毫米，长在穗状分枝上，所有的雄蕊凸出。

Echium plantagineum, commonly known as purple viper's-bugloss or Paterson's curse, is a species of Echium native to western and southern Europe (from southern England south to Iberia and east to the Crimea), northern Africa, and southwestern Asia (east to Georgia). It has also been introduced to Australia, South Africa and United States, where it is an invasive weed. Due to a high concentration of pyrrolizidine alkaloids, it is poisonous to grazing livestock, especially those with simple digestive systems, like horses. The toxins are cumulative in the liver, and death results from too much Paterson's curse in the diet.
