Baby Gem Boxwood
Buxus microphylla ‘Gregem’ · a rounded boxwood
A dwarf Japanese boxwood with tiny leaves that grows into a naturally dense, neat mound, so it needs less clipping than most. It makes a fine low hedge, edging or foundation planting, and Japanese boxwood is highly resistant to boxwood blight. Grow it in sun or part shade, in soil that never stays wet.

Spacing for a hedge
VeraScape spaces plants so their grown canopies just touch. For Baby Gem Boxwood, that’s about 4.5 ft apart, center to center.
