Golden rain tree pods.""William Maclure wanted to raise a kind of tree known as the ""pride of China," also known today as ""golden rain tree." In 1829, after Maclure had moved from New Harmony to Mexico, he acquired seeds but was unable to get them to germinate. In hopes that they would do better in New Harmony, seeds were sent to Thomas Say. He was successful, and today there are many golden rain trees in New Harmony and the surrounding region. Local tradition holds that the New Harmony naturalists introduced the golden raintree to America, but in fact, credit for this introduction belongs to Thomas Jefferson, dating from 1809." (https://faculty.evansville.edu/ck6/bstud/raintree.html) William Maclure, the ""father of American geology," was a collaborator with Robert Owen in his social experiments with community at New Harmony. Thomas Say was an American naturalist who traveled to New Harmony on the ""Boatload of Knowledge"" and continued to work there until his death.
