Echinops ritro, the southern globethistle, is a species of flowering plant in the sunflower family, native to southern and eastern Europe (from Spain east to Turkey, Ukraine, and Belarus), and western Asia.[2] The species is sparingly naturalized in scattered locations in the United States.[3][4]

Echinops ritro is a compact, bushy herbaceous perennial thistle, growing to 60 cm (24 in) tall, with broad prickly leaves and bearing globes of steel-blue flowers 2.5 cm - 4.5 cm in diameter, in late summer.[5]

Echinops ritro [6] and the subspecies E. ritro subsp. ruthenicus[7] have gained the Royal Horticultural Society's Award of Garden Merit.
