Any householder who grows peonies knows that Chinese plant species thrive in North America and other temperate regions around the world. Although few gardeners may know the history, the peonies so familiar and beloved in America are not native species, such as Paeonia brownii Douglas, but rather descendants of Paeonia lactiflora Pall. cultivars developed in China centuries ago, introduced into Europe around 1800, and from there imported to the New World.
