Easily grown in well-drained soil in full sun to part shade. Tolerates wide range of soils.  Evergreen in protected areas.  Can suffer some tip dieback in unprtected areas. New growth comes back nicely each spring. Can be mowed in late fall or early winter every 2-3 years to renew and induce new growth. Spreads rapidly by underground stems and can spread aggressively in ideal growing conditions. Plant 18" apart for use as a ground cover.

Also effective massed on slopes, hillsides or embankments for stabilizing soils. Plant under trees where it competes well with shallow tree roots.
