Shrubs
Buxus microphylla 'Robbuxupt'
Uptight® boxwood
Dense branching and deep green foliage form a naturally upright, columnar shrub. This boxwood adds evergreen height to foundation beds, hedges and specimen plantings. Its narrower outline provides structure without the broad spread of many rounded boxwood selections.
