Granny Smith is the iconic green apple, famous worldwide for its bright green skin and exceptionally tart, crisp flesh. Originating from Australia in 1868, this versatile variety thrives in Zones 6-9, preferring warmer climates with long growing seasons. Trees reach 12-18 feet and produce large, firm fruit ideal for baking, cooking, fresh eating, and salads—the slow-browning flesh maintains appearance beautifully. Harvest occurs late October through November. Granny Smith requires cross-pollination with varieties like Fuji, Gala, or Red Delicious. Outstanding storage capability (up to 6 months refrigerated) and distinctive tart flavor make it indispensable for culinary applications. The vigorous, spreading trees deliver consistent heavy yields, while the fruit's firmness ensures excellent shipping and handling qualities for commercial operations.
