This plant, also known as a Sea Holly, bears strange and spiky purplish blossoms. It thrives even in poor soil and hot, dry conditions. Even when not in bloom, the serrated, wavy leaves arising in a rosette pattern from a central tap root are interesting and can provide a textural contrast in the border.

The blossoms are long-lasting as cut flowers, and a real conversation piece in a bouquet!
