Plant in moist, well-drained soil in sun or partial shade where it will thrive, though it will also tolerate full shade. It's a spreading ground cover, so it space to form a mat, and avoid planting too close to other low-growing plants.
Keep watered in dry spells until established, then it’s generally low maintenance. Cut back any faded flower spikes and trim back runners if they spread too far.
To rejuvenate and minimise congestion, lift and divide clumps in late autumn or early spring every few years.
