Columnar Apple Tree (White Icicle)

Description White Icicle™ is built for growers who love a sharp, refreshing apple. Its naturally upright, columnar form stays narrow and vertical, fruiting along the main leader rather than spreading outward—making it easy to grow real apples in spaces where traditional trees don’t fit. The fruit ripens mid-season with a crisp texture and a distinctly tart, green-apple profile. White Icicle™ is meant to be eaten firm, delivering brightness and bite rather than sweetness, and serving as a clear contrast to dessert-style columnar apples. Adding to its appeal is a notably pale, almost white interior flesh paired with green skin—an uncommon visual combination that reinforces its clean, refreshing character and explains the name.
