The Uptight Boxwood lives up to its name – it is tight and dense in structure, even with little or no trimming, and it grows up, not out, different from most other boxwoods. This rapid-growing form of Korean boxwood is remarkable for naturally growing 5 to 7 feet tall and staying just 3 feet wide. In addition, it is hardy into zone 4, and shows no bronzing or browning at all at low temperatures that brown other well-known forms of Korean boxwood. Because it grows naturally upright, it is ideal for making those pyramids, cones and tear-drop shapes that add such wonderful accents to any garden. Its upright shape also means it is easy to grow a tall boxwood hedge in the shortest possible time.
Anything from full sun to light full shade will suit the Uptight Boxwood. It will grow in any kind of soil that is not regularly soaked in water. Once established it will tolerate normal periods of drought, but it benefits from a good supply of water and fertilizer, especially if you want to maximize its growth rate and strong green coloring. It is also free of any significant pests or diseases, and it is not even bothered by deer. This ‘always green’ variety is the best boxwood for upright specimens or taller hedges available, especially in cold, exposed areas.
