Answer: I would recommend planting a true dwarf boxwood, Korean Boxwood (koreana x sempervirens). You have your choice between:
'Green Gem': a green mound; requires little pruning; slow-growing, deep green foliage throughout winter. Grows 2 by 2'.
'Green Velvet': similar to Green Gem in foliage; rounded, full-bodied, and slow-growing. Grows 4 x 4'.
'Winter Gem': grows 2' high; very hardy for cold weather climates.
'Wintergreen': Grows 3-4' by 3'-4'.
