The Brogdon avocado tree is a cold-hardy, fast-growing, and highly productive cultivar known for its dark purple-black skin and rich, nutty flavor, making it ideal for USDA Zones 8b to 11. It is a Type B bloomer that thrives in full sun, grows up to 20–30 feet (but is manageable through pruning), and offers a high-quality, creamy fruit with thin, edible skin that matures from July to October.
