Purple Sheep's Burr (Acaena inermis 'Purpurea'): New Zealand Groundcover with Scalloped Purple Leaves

Overview

'Purpurea' is a striking New Zealand native subshrub forming a low mat less than 6 inches tall and spreading 1–3 feet wide. The 3-inch-wide scalloped leaves are deep purple-brown to pale olive. In early summer, ¾-inch flowers appear on short stems with brownish-green sepals and white anthers contrasting with the dark foliage. Rhizomatous roots spread slowly.

Cultivation

Full sun, well-drained sandy soil. Hardy in zones 6–9. Low maintenance; prune every 5 years for neatness. Drought tolerant once established.

Landscape Uses

Excellent groundcover for rock gardens, gravel gardens, and between pavers. The unique purple foliage provides year-round color. Combines with silver, gold, and green foliage plants.
