Additional information  
Several cultivars of Amur maackia have been selected for improved flowering, foliage quality, and/or growth habit.  A few recommended varieties include ‘Summertime’, ‘Starburst’, and the newer ‘JFS-Schichtel1’ (sold as MaacNificent®) which features a more upright, vase-shaped crown than is typical for the species.
