Echinops ritro 'Blue Globe Thistle' Plants

The globe thistle is a strong upright perennial that is topped with globe shaped flowers from May-July; or until September if sheared to prevent seed production.  The heavily serrated blue-green leaves have white undersides and provide the garden with unique texture in early spring and late fall.  Echinops ritro is one of the most cold hardy perennials you can buy.  Great for the perennial border and makes a nice back drop for lighter colored perennials.
