Comments
Trailing habit makes it suitable to cover banks or cascade over walls, but can serve as cover for flat spots.  Plants resist drought, but benefit from watering during extended heat.  Tolerates poor soil.  Space plants 18 to 24 inches apart.  Discard old woody plants every fourth year and use younger plants from the divisions for replanting in early spring.  Mulch new planting to control weeds
