Description
Scarlet Sentinel™ delivers classic red-apple flavor on a tree designed for modern spaces. Its upright, columnar form fruits along the main leader rather than spreading outward, turning patios, walkways, and small gardens into productive apple plantings without sacrificing flavor. The apples ripen in late September with a clean, balanced profile—sweet enough for fresh eating, with enough acidity to stay lively. The texture is crisp and refreshing, making Scarlet Sentinel™ an easy, everyday apple for small-space growers. Like other true columnar apples, Scarlet Sentinel™ traces back to the McIntosh columnar mutation first identified in Canada, a genetic foundation that allows compact trees to carry real, full-sized fruit rather than novelty harvests.
