A very good selection of the nigra birch, found in America. Grows rapidly into an average-sized, graceful tree with pendent branches. At a young age the trunk is white-silvery and it retains this colour when maturing. The bark peels. Young twigs are red brown with dark lenticels. The leaf is shiny and deep green and turns to yellow in autumn. 'Heritage' has an early inflorescence, very abundant and because of the 8 cm long male catkins very striking. Originally growing in moist soil, but also thriving in drier locations. The tree is shallow-rooted and has a delicate root system and many fibrous rootlets. This variety is very suitable for use in warm areas, but is hardy too. 'Heritage' is resistant to the bronze birch borer which can often be found in America.
