The Franklinia tree (*Franklinia alatamaha*), a rare and beautiful flowering plant, is often admired for its striking white blossoms and vibrant fall foliage. But can you grow a small Franklinia in an outdoor plant box? The answer is yes—with the right conditions and care.

Franklinia trees are typically small, reaching heights of 10-20 feet, making them suitable for container gardening. When planting in an outdoor plant box, ensure the container is large enough to accommodate the tree's root system—at least 18-24 inches in diameter and depth. Use well-draining, acidic soil (pH 5.0-6.5) to mimic its natural habitat.

Place the plant box in a location with partial to full sunlight, as Franklinia thrives in bright but not scorching conditions. Water regularly to keep the soil moist but not waterlogged, and protect the tree from harsh winds.

While Franklinia is hardy in USDA zones 5-8, container-grown trees may need extra winter protection, such as mulching or moving the box to a sheltered area. With proper care, your small Franklinia can flourish in an outdoor plant box, adding elegance to patios, balconies, or small gardens.
