What two trees did Ponce de Leon introduce to Florida in 1513?

But nowhere on earth, or perhaps even the heavens, has the “golden fruit” held more importance than in Florida, where citrus growing and processing has become a multi-billion dollar industry. Christopher Columbus brought the first citrus to the New World in 1493. The early Spanish explorers, probably Ponce de Leon, planted the first orange trees around St. Augustine, Florida, sometime between 1513 and 1565. The heritage left behind in citrus was destined to blossom into industries worth billions of dollars.
