Commonly known as the 'Hedgehog Dianthus' and the name describes it well - tight little buns with sharp, spiny grey leaves, just like a curled-up hedgehog. Studded with tiny pink flowers in summer. More than a novelty with a cute name, Dianthus erinaceus is a fine, slow-growing plant. It would do well in a stone trough or container but is equally suited to the rockery. Very hardy.
It is very deep-rooted when established so should be drought resistant if grown in the ground and is very long-lived. Only 5 to 7cm (2" or 3") high, but can eventually (after many years) form impressive mounds.
