Purple sheep’s burr

Acaena inermis 'Purpurea'

ah-SEE-nah ih-NER-mis

This New Zealand native subshrub has 3-inch-wide scalloped leaves and little 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, 3/4-inch-wide flowers appear on short stems, and brownish green sepals and white anthers contrast with the dark leaves. The rhizomatous roots of this plant spread slowly into a mat, forming a nice ground cover. Prune every five years or so for a neat appearance; little other care is required. -Gerald Gibbens, Regional Picks: Northwest, Fine Gardening issue #120
