Sky Box Japanese Holly

Sky Box® Japanese Holly is the compact evergreen cultivar Ilex crenata 'Farrowone' (PP#20,049), with glossy dark-green foliage and a narrow pyramidal outline. The [official cultivar page](https://www.provenwinnerscolorchoice.com/product/sky-box-japanese-holly/) lists USDA hardiness zones 5–8, mature dimensions of 4–5 feet tall by 2–3 feet wide, white flowers on old wood, and full sun to part sun. ## Landscape Use Use it as a hedge, grouped planting, or formal accent where a compact evergreen shape is useful. Its dense branching keeps the plant full, and it tolerates shade, although its color and form are strongest with more sun. ## Site and Growing Conditions Choose full sun or part sun and moist, well-drained soil. Sky Box prefers acidic soil but adapts to a range of conditions; alkaline soil can lead to yellowing foliage (chlorosis). Its evergreen leaves provide structure throughout the year. ## Maintenance Routine pruning is not needed. If you want to refine the outline, prune in late winter or early spring. Regular fertilizer is also unnecessary, though the official source notes that an optional spring application can be made when the soil is workable.
