Prince of Wales Juniper (Juniperus horizontalis ‘Prince of Wales’) is a low-growing, spreading evergreen shrub widely used as a hardy groundcover in prairie landscapes. It forms a dense, mat-like carpet of soft, fine-textured green foliage that often takes on a subtle purplish-bronze tint in winter. The plant spreads outward by trailing stems that root as they grow, making it excellent for erosion control on slopes, rock gardens, and low-maintenance beds. In Regina’s climate, it is exceptionally hardy and dependable, maintaining year-round structure and colour even in harsh winter conditions.
