Source: Fine Gardening Magazine - This subshrub from New Zealand has scalloped leaves that reach 3 inches across with 11 to 15 tiny, purple-brown to pale olive leaflets. Its rhizomatous roots spread in a mat to support this plant's wonderful ground-cover form. In early summer, the flower stems rise nearly 3 inches tall, ending with numerous 3/4-inch-wide flowers composed of brownish green sepals and white anthers. Purple sheep's burr spreads slowly until well established. It requires little attention, other than pruning every five years or so to tidy things up.
Noteworthy characteristics: Scalloped, purple leaves. Low maintenance.
