In some situations, an alternative shade groundcover may be a better option. Keep in mind poor soil drainage can be a problem. Also, groundcovers are low maintenance plantings, but they still require some attention. Here is a rundown of some potential choices. Ajuga or bugleweed is popular.
Many cultivars are available, with variations in both flower and foliage color.
Ajuga can grow in sun or shade, and reaches 4-6 inches in height. This plant has fairly shallow roots, and spreads via stolons. Vinca minor or periwinkle is vinelike in growth, rooting as it creeps along the ground. It can be planted in sun or shade, but avoid wet sites and protect from winter winds. Periwinkle has lilac to blue flowers.
