Care & Maintenance
Low maintenance and mildew-resistant. If foliage looks tired in hot summers, give it a light shear after flowering to refresh the plant and encourage a second flush of growth. Some susceptibility to leaf spots and rust — good air circulation helps.
Landscape Uses
Ideal for accents or mass plantings in borders, woodland gardens, rock gardens, foundation plantings, and containers. Its spreading habit makes it a natural groundcover for slopes and garden edges.
