Pachystegia rufa, commonly known as the Marlborough rock daisy, is an evergreen shrub native to New Zealand, naturally occurring on rocky coastal cliffs and limestone outcrops in the upper South Island. It forms a compact, rounded habit with large, leathery leaves that are dark green above and covered in distinctive rusty-brown felt beneath. In summer, it produces large white daisy-like flowers with yellow centres, creating a striking display against the bold foliage and thrives in dry, rocky conditions once established. It is commonly used in coastal gardens, rock gardens, and native landscapes, valued for its architectural foliage and resilience.
