Growing & Maintenance Tips
This drought-tolerant cultivar can be planted in full sun or partial shade in an average, well-drained soil. It will thrive with little or no care and is suitable for dry slopes or other low maintenance sites. Can spread very quickly.
Notes
Almost invasive. If it'll grow 'vigorously' in full sun, it'll bear watching.
