She grows with vigor, forms a robust canopy, and stands tall where others may falter—especially in cooler climates or areas where citrus diseases run rampant.
Even without a grafted variety on top, she’s worth growing to appreciate the structure, the strength, and the future possibilities she holds.
In every good Southern garden, there ought to be at least one tree that teaches resilience. This is that tree. Citrus US‑1516 is as much promise as it is plant. She’ll take root where others fail, and give you a foundation—whether for fruit, or for hope.
