Bonpland was freed in 1829 and in 1831 returned to Argentina, where he settled at San Borja in Corrientes. There, aged 58, he married a local woman and made a living farming and trading in yerba mate. In 1853, he returned to Santa Ana, where he cultivated the orange trees he had introduced. He received a piastre estate from the Corrientes government in gratitude for his work in the province. The small town around it is now known as "Bonpland" in his honor. A different small town in Misiones province just south of Santa Ana (Misiones) is also named Bonpland.
