Plant profile: Eryngium
Also known as sea holly, Eryngium belongs to the carrot or Apiaceae family: most species form basal leaf rosettes and bear thistle-like umbels of stalkless flowers on branched stems. The perennials that we grow tend to be cultivars rather than wild forms, and are derived from just a few Eurasian species.
