'Graham Blandy' Columnar Boxwood

Buxus sempervirens ‘Graham Blandy’ is a narrow, upright evergreen boxwood with small dark green leaves. Its columnar shape gives vertical structure in a compact footprint, making it suitable for a formal accent, narrow planting space, or clipped hedge. ## Size and siting The [JC Raulston Arboretum at NC State](https://jcra.ncsu.edu/horticulture/our-plants/results-by-name-serial-number.php?serial=100686) records the cultivar at about 8–10 feet tall by 2 feet wide, with evergreen foliage and part-sun to part-shade exposure; Use part sun to part shade and allow room for its narrow 8–10 foot column. Site in well-drained soil and avoid persistently soggy conditions. Boxwood can be affected by blight, leafminer, and other pests, so inspect plants and allow airflow through dense growth. ## Maintenance Use selective thinning to keep light and air moving through the shrub. If a tightly clipped outline is desired, trim lightly after growth and avoid repeatedly shearing the same outer surface into a dense shell. Water new plantings during dry periods and at the base to limit leaf wetness. [University of Maryland Extension](https://extension.umd.edu/resource/boxwood-identify-and-manage-common-problems) notes that thinning supports interior airflow and that repeated shearing can increase fungal disease risk.
