- Hardy to USDA Zone (4)5 Native to central and western China. It was introduced into cultivation from seeds collected in China by Ernest Wilson in 1907. Similar to Maackia amurensis in appearance, but according to Jacobson (1996, p. 315) Maackia chinensis is a "superior ornamental, being less coarse, with more slender twigs and finer foliage." Foliage texture similar to that of Robinia and Sophora.
