Sprinter boxwood (Buxus microphylla 'Sprinter®') gives you classic, tidy evergreen structure with a naturally dense habit that looks at home in both formal and informal designs. You can use it to edge a walkway, frame a foundation, or build a low hedge that fills in quickly for its mature size. Expect it to reach about 24-48 inches tall with a similar spread, depending on your pruning style and growing conditions.
Plant it in full sun, part sun/part shade, or even bright shade. In general, you will see the fastest, fullest growth with more sun, while plants in deeper shade tend to grow more slowly and may look a bit looser. Choose a site with well-drained soil, and avoid low spots where water stands after rain.
After planting, keep the root zone evenly moist until the shrub is established. Once rooted in, water during dry spells; steady moisture reduces stress that can invite pests and leaf problems. Mulch helps moderate soil temperature, but keep mulch pulled back from the stems so air can circulate at the base of the plant.
Pruning is optional: you can leave it to form a neat mound or shear it lightly to maintain a crisp outline. If you do prune, trim after the flush of new growth and avoid cutting back into thick, leafless wood. Because it is an evergreen, protect it from winter wind and winter drought by watering in fall during dry weather and providing a sheltered location when possible.
