Peach trees, Prunus persica, are originally believed to have come from China to the Mideast through the trade routes known to extend to Turkey and Iran (Persia).
Christopher Columbus in 1493 introduced citrus trees into America on the Island of Haiti, by planting the seed of the sweet orange tree, the sour orange, citron, lemon, lime, and pummelo fruit trees.
Apricots originated on the Russian-Chinese border in about 3000 BC and were imported along with peach seed into Europe through the "Silk Road" that extended camelback trading to the Mideast.
