The Wintergreen Boxwood (Buxus sinica var. insularis 'Wintergreen'), also known as the Korean Boxwood, is one of the hardiest and most versatile boxwood varieties. The "Cone" designation typically refers to a plant that has been topiaried (pruned) into a formal upright cone shape at the nursery, a style for which this variety is perfectly suited. When grown or pruned into a cone shape, the Wintergreen Boxwood provides a very formal, architectural look. The foliage is incredibly dense and fine-textured, creating a solid "wall" of green. Because it grows slowly, it holds its manicured shape for a long time, requiring only one or two light prunings per year. It is a favorite for flanking entryways, sitting in large decorative pots, or adding structure to the corners of garden beds.

Plant Care & Characteristics

Light Requirements: Full Sun to Partial Shade. It is highly adaptable. In hotter climates (Zones 8-9), it actually prefers some afternoon shade to prevent the leaves from "scorching" or bronzing.

Water Requirements: Moderate. It needs regular watering during its first two years to establish a deep root system. Once established, it is relatively self-sufficient but appreciates a deep soak during extreme summer heat. Avoid watering with overhead sprinklers; instead, water at the base of the plant to keep the foliage dry, which prevents fungal issues like Boxwood Blight.

Drought Resistance: Moderate. It is more drought-tolerant than many other boxwood varieties, but it will show stress (leaf drop) if the soil remains bone-dry for extended periods.

Soil Type: Well-Drained. This is the most critical factor. Boxwoods are susceptible to root rot in "wet feet." They prefer a slightly acidic to neutral pH and thrive in loamy soil amended with organic matter.

Deer Resistance: High. Boxwoods contain alkaloids that are distasteful and toxic to deer, so they are generally left completely alone.
