Korean boxwood 'Wintergreen'

Buxus sinica var. insularis 'Wintergreen'

Preview: plant data is awaiting horticulturist review. A professional horticulturist hasn't reviewed our plant table yet. Lists still follow fixed rules for zone, sun, pets, deer and invasive status.

Hardy in zones 4–9, Korean boxwood 'Wintergreen' is a slow-growing evergreen shrub. Expect 2–4 ft of height and 3–5 ft of spread; our lists space it 3.5 ft apart. It does best in full sun to part shade with average water. It is grown for its year-round foliage rather than its flowers. In a FloraVista list it usually plays the structure role: a shrub that holds the bed's shape at the back all year. Deer usually leave it alone, and it is toxic to dogs and cats. Our rules leave it out of lists in the Desert Southwest, where summer heat, humidity or mild winters hold it back even inside its zone range.
