As discussed a few weeks ago, growing a quality lawn in the shade can be very difficult. 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's a rundown of some potential choices.
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. It's best to locate in a spot protected from winter winds. Pachysandra features evergreen foliage and reaches about one foot or so in height. Winter wind, full sun, and poor soil drainage can be problems.
